Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553366, here are decompositions:

7 + 31553359 = 31553366
277 + 31553089 = 31553366
349 + 31553017 = 31553366
367 + 31552999 = 31553366
487 + 31552879 = 31553366
619 + 31552747 = 31553366
673 + 31552693 = 31553366
727 + 31552639 = 31553366

Showing the first eight; more decompositions exist.
