Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495576, here are decompositions:

53 + 31495523 = 31495576
59 + 31495517 = 31495576
83 + 31495493 = 31495576
107 + 31495469 = 31495576
113 + 31495463 = 31495576
173 + 31495403 = 31495576
389 + 31495187 = 31495576
419 + 31495157 = 31495576

Showing the first eight; more decompositions exist.
