Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538996, here are decompositions:

109 + 31538887 = 31538996
277 + 31538719 = 31538996
283 + 31538713 = 31538996
367 + 31538629 = 31538996
373 + 31538623 = 31538996
439 + 31538557 = 31538996
457 + 31538539 = 31538996
523 + 31538473 = 31538996

Showing the first eight; more decompositions exist.
