Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555314, here are decompositions:

17 + 31555297 = 31555314
47 + 31555267 = 31555314
61 + 31555253 = 31555314
71 + 31555243 = 31555314
103 + 31555211 = 31555314
127 + 31555187 = 31555314
157 + 31555157 = 31555314
173 + 31555141 = 31555314

Showing the first eight; more decompositions exist.
