Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510332, here are decompositions:

11 + 31510321 = 31510332
13 + 31510319 = 31510332
23 + 31510309 = 31510332
89 + 31510243 = 31510332
109 + 31510223 = 31510332
163 + 31510169 = 31510332
193 + 31510139 = 31510332
199 + 31510133 = 31510332

Showing the first eight; more decompositions exist.
