Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553182, here are decompositions:

5 + 31553177 = 31553182
113 + 31553069 = 31553182
239 + 31552943 = 31553182
263 + 31552919 = 31553182
449 + 31552733 = 31553182
461 + 31552721 = 31553182
593 + 31552589 = 31553182
761 + 31552421 = 31553182

Showing the first eight; more decompositions exist.
