Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511734, here are decompositions:

5 + 31511729 = 31511734
83 + 31511651 = 31511734
197 + 31511537 = 31511734
251 + 31511483 = 31511734
257 + 31511477 = 31511734
263 + 31511471 = 31511734
311 + 31511423 = 31511734
503 + 31511231 = 31511734

Showing the first eight; more decompositions exist.
