Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511482, here are decompositions:

5 + 31511477 = 31511482
11 + 31511471 = 31511482
59 + 31511423 = 31511482
251 + 31511231 = 31511482
269 + 31511213 = 31511482
293 + 31511189 = 31511482
311 + 31511171 = 31511482
479 + 31511003 = 31511482

Showing the first eight; more decompositions exist.
