Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509704, here are decompositions:

7 + 31509697 = 31509704
13 + 31509691 = 31509704
43 + 31509661 = 31509704
103 + 31509601 = 31509704
151 + 31509553 = 31509704
181 + 31509523 = 31509704
271 + 31509433 = 31509704
367 + 31509337 = 31509704

Showing the first eight; more decompositions exist.
