Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522762, here are decompositions:

149 + 31522613 = 31522762
179 + 31522583 = 31522762
233 + 31522529 = 31522762
239 + 31522523 = 31522762
269 + 31522493 = 31522762
311 + 31522451 = 31522762
389 + 31522373 = 31522762
431 + 31522331 = 31522762

Showing the first eight; more decompositions exist.
