Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555088, here are decompositions:

7 + 31555081 = 31555088
67 + 31555021 = 31555088
127 + 31554961 = 31555088
139 + 31554949 = 31555088
199 + 31554889 = 31555088
277 + 31554811 = 31555088
349 + 31554739 = 31555088
379 + 31554709 = 31555088

Showing the first eight; more decompositions exist.
