Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510482, here are decompositions:

23 + 31510459 = 31510482
79 + 31510403 = 31510482
83 + 31510399 = 31510482
163 + 31510319 = 31510482
173 + 31510309 = 31510482
239 + 31510243 = 31510482
313 + 31510169 = 31510482
349 + 31510133 = 31510482

Showing the first eight; more decompositions exist.
