Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582832, here are decompositions:

13 + 31582819 = 31582832
103 + 31582729 = 31582832
199 + 31582633 = 31582832
223 + 31582609 = 31582832
433 + 31582399 = 31582832
499 + 31582333 = 31582832
661 + 31582171 = 31582832
739 + 31582093 = 31582832

Showing the first eight; more decompositions exist.
