Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582796, here are decompositions:

19 + 31582777 = 31582796
67 + 31582729 = 31582796
163 + 31582633 = 31582796
283 + 31582513 = 31582796
307 + 31582489 = 31582796
379 + 31582417 = 31582796
397 + 31582399 = 31582796
463 + 31582333 = 31582796

Showing the first eight; more decompositions exist.
