Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555114, here are decompositions:

5 + 31555109 = 31555114
53 + 31555061 = 31555114
83 + 31555031 = 31555114
167 + 31554947 = 31555114
251 + 31554863 = 31555114
263 + 31554851 = 31555114
317 + 31554797 = 31555114
443 + 31554671 = 31555114

Showing the first eight; more decompositions exist.
