Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553588, here are decompositions:

61 + 31553527 = 31553588
229 + 31553359 = 31553588
499 + 31553089 = 31553588
571 + 31553017 = 31553588
709 + 31552879 = 31553588
757 + 31552831 = 31553588
907 + 31552681 = 31553588
967 + 31552621 = 31553588

Showing the first eight; more decompositions exist.
