Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529206, here are decompositions:

239 + 31528967 = 31529206
353 + 31528853 = 31529206
383 + 31528823 = 31529206
509 + 31528697 = 31529206
593 + 31528613 = 31529206
647 + 31528559 = 31529206
659 + 31528547 = 31529206
773 + 31528433 = 31529206

Showing the first eight; more decompositions exist.
