Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553716, here are decompositions:

53 + 31553663 = 31553716
107 + 31553609 = 31553716
197 + 31553519 = 31553716
263 + 31553453 = 31553716
347 + 31553369 = 31553716
443 + 31553273 = 31553716
503 + 31553213 = 31553716
647 + 31553069 = 31553716

Showing the first eight; more decompositions exist.
