Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582262, here are decompositions:

13 + 31582249 = 31582262
79 + 31582183 = 31582262
241 + 31582021 = 31582262
373 + 31581889 = 31582262
379 + 31581883 = 31582262
619 + 31581643 = 31582262
853 + 31581409 = 31582262
883 + 31581379 = 31582262

Showing the first eight; more decompositions exist.
