Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582508, here are decompositions:

19 + 31582489 = 31582508
37 + 31582471 = 31582508
109 + 31582399 = 31582508
241 + 31582267 = 31582508
337 + 31582171 = 31582508
487 + 31582021 = 31582508
547 + 31581961 = 31582508
619 + 31581889 = 31582508

Showing the first eight; more decompositions exist.
