Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555062, here are decompositions:

31 + 31555031 = 31555062
41 + 31555021 = 31555062
43 + 31555019 = 31555062
101 + 31554961 = 31555062
113 + 31554949 = 31555062
163 + 31554899 = 31555062
173 + 31554889 = 31555062
179 + 31554883 = 31555062

Showing the first eight; more decompositions exist.
