Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495508, here are decompositions:

7 + 31495501 = 31495508
61 + 31495447 = 31495508
151 + 31495357 = 31495508
157 + 31495351 = 31495508
337 + 31495171 = 31495508
571 + 31494937 = 31495508
601 + 31494907 = 31495508
691 + 31494817 = 31495508

Showing the first eight; more decompositions exist.
