Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509424, here are decompositions:

5 + 31509419 = 31509424
17 + 31509407 = 31509424
53 + 31509371 = 31509424
101 + 31509323 = 31509424
173 + 31509251 = 31509424
251 + 31509173 = 31509424
347 + 31509077 = 31509424
503 + 31508921 = 31509424

Showing the first eight; more decompositions exist.
