Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509496, here are decompositions:

89 + 31509407 = 31509496
167 + 31509329 = 31509496
173 + 31509323 = 31509496
419 + 31509077 = 31509496
443 + 31509053 = 31509496
467 + 31509029 = 31509496
479 + 31509017 = 31509496
653 + 31508843 = 31509496

Showing the first eight; more decompositions exist.
