COMMENTS
This is related to Goldbach's conjecture, since entries for which the leftmost entry and the top entry are both nonzero are the sums of two primes.
The successive antidiagonals may also be regarded as the rows of a triangle, having A101264 as outside diagonals.
EXAMPLE
Beginning of the array. All elements are equal to topmost value plus leftmost value.
