Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582502, here are decompositions:

13 + 31582489 = 31582502
31 + 31582471 = 31582502
103 + 31582399 = 31582502
181 + 31582321 = 31582502
331 + 31582171 = 31582502
409 + 31582093 = 31582502
499 + 31582003 = 31582502
541 + 31581961 = 31582502

Showing the first eight; more decompositions exist.
