Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509610, here are decompositions:

17 + 31509593 = 31509610
53 + 31509557 = 31509610
179 + 31509431 = 31509610
191 + 31509419 = 31509610
239 + 31509371 = 31509610
281 + 31509329 = 31509610
359 + 31509251 = 31509610
389 + 31509221 = 31509610

Showing the first eight; more decompositions exist.
