Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33515172, here are decompositions:

13 + 33515159 = 33515172
43 + 33515129 = 33515172
73 + 33515099 = 33515172
113 + 33515059 = 33515172
139 + 33515033 = 33515172
151 + 33515021 = 33515172
373 + 33514799 = 33515172
479 + 33514693 = 33515172

Showing the first eight; more decompositions exist.
