Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611526, here are decompositions:

17 + 31611509 = 31611526
53 + 31611473 = 31611526
59 + 31611467 = 31611526
197 + 31611329 = 31611526
227 + 31611299 = 31611526
389 + 31611137 = 31611526
503 + 31611023 = 31611526
509 + 31611017 = 31611526

Showing the first eight; more decompositions exist.
