Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509634, here are decompositions:

5 + 31509629 = 31509634
17 + 31509617 = 31509634
41 + 31509593 = 31509634
227 + 31509407 = 31509634
263 + 31509371 = 31509634
311 + 31509323 = 31509634
383 + 31509251 = 31509634
461 + 31509173 = 31509634

Showing the first eight; more decompositions exist.
