Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509602, here are decompositions:

31 + 31509571 = 31509602
73 + 31509529 = 31509602
79 + 31509523 = 31509602
199 + 31509403 = 31509602
331 + 31509271 = 31509602
433 + 31509169 = 31509602
463 + 31509139 = 31509602
541 + 31509061 = 31509602

Showing the first eight; more decompositions exist.
