Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503682, here are decompositions:

113 + 31503569 = 31503682
173 + 31503509 = 31503682
239 + 31503443 = 31503682
359 + 31503323 = 31503682
479 + 31503203 = 31503682
503 + 31503179 = 31503682
563 + 31503119 = 31503682
719 + 31502963 = 31503682

Showing the first eight; more decompositions exist.
