EXAMPLE

a(1) = 33 because the smallest number n with A223730(n) = 2 is 33. The two representations of 33 are denoted by [1, 4, 4], and [2, 2, 5].
The two representations for a(n) for n = 2..10 are denoted by
n=2, 38: [1, 1, 6], [2, 3, 5],
n=3, 41: [1, 2, 6], [3, 4, 4],
n=4, 51: [1, 1, 7], [1, 5, 5],
n=4, 54: [1, 2, 7], [2, 5, 5], ([3, 3, 6] is nonprimitive)
n=5, 57: [2, 2, 7], [4, 4, 5],
n=6, 59: [1, 3, 7], [3, 5, 5],
n=7, 62: [1, 5, 6], [2, 3, 7],
n=8, 69: [1, 2, 8], [2, 4, 7],
n=9, 74: [1, 3, 8], [3, 4, 7],
n=10, 77: [2, 3, 8], [4, 5, 6].
