Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582082, here are decompositions:

61 + 31582021 = 31582082
79 + 31582003 = 31582082
109 + 31581973 = 31582082
193 + 31581889 = 31582082
199 + 31581883 = 31582082
223 + 31581859 = 31582082
373 + 31581709 = 31582082
409 + 31581673 = 31582082

Showing the first eight; more decompositions exist.
