Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499410, here are decompositions:

3 + 31499407 = 31499410
11 + 31499399 = 31499410
23 + 31499387 = 31499410
83 + 31499327 = 31499410
101 + 31499309 = 31499410
113 + 31499297 = 31499410
179 + 31499231 = 31499410
227 + 31499183 = 31499410

Showing the first eight; more decompositions exist.
