Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509344, here are decompositions:

7 + 31509337 = 31509344
37 + 31509307 = 31509344
73 + 31509271 = 31509344
127 + 31509217 = 31509344
283 + 31509061 = 31509344
313 + 31509031 = 31509344
397 + 31508947 = 31509344
457 + 31508887 = 31509344

Showing the first eight; more decompositions exist.
