Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495762, here are decompositions:

5 + 31495757 = 31495762
29 + 31495733 = 31495762
71 + 31495691 = 31495762
101 + 31495661 = 31495762
173 + 31495589 = 31495762
239 + 31495523 = 31495762
251 + 31495511 = 31495762
269 + 31495493 = 31495762

Showing the first eight; more decompositions exist.
