Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552502, here are decompositions:

13 + 31552489 = 31552502
73 + 31552429 = 31552502
109 + 31552393 = 31552502
151 + 31552351 = 31552502
193 + 31552309 = 31552502
199 + 31552303 = 31552502
433 + 31552069 = 31552502
523 + 31551979 = 31552502

Showing the first eight; more decompositions exist.
