This sequence contains probably every natural number, though this should be checked further. Conjecture: Every prime >=5 can be represented as a sum of at most 3 primes, such that all the previous odd primes are represented.
EXAMPLE
5=2+3->1 step
7=2+2+3=2+5->2 steps
11=2+2+7=3+3+5->2 steps
13=2+11=3+5+5=3+3+7->3 steps
41=2+2+37=3+7+31=5+7+29=5+13+23=5+17+19=11+13+17->6 steps
