Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555036, here are decompositions:

5 + 31555031 = 31555036
17 + 31555019 = 31555036
89 + 31554947 = 31555036
137 + 31554899 = 31555036
173 + 31554863 = 31555036
239 + 31554797 = 31555036
419 + 31554617 = 31555036
467 + 31554569 = 31555036

Showing the first eight; more decompositions exist.
