Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495504, here are decompositions:

3 + 31495501 = 31495504
11 + 31495493 = 31495504
23 + 31495481 = 31495504
41 + 31495463 = 31495504
101 + 31495403 = 31495504
137 + 31495367 = 31495504
263 + 31495241 = 31495504
317 + 31495187 = 31495504

Showing the first eight; more decompositions exist.
