Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553066, here are decompositions:

3 + 31553063 = 31553066
67 + 31552999 = 31553066
373 + 31552693 = 31553066
463 + 31552603 = 31553066
487 + 31552579 = 31553066
577 + 31552489 = 31553066
673 + 31552393 = 31553066
757 + 31552309 = 31553066

Showing the first eight; more decompositions exist.
