Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553062, here are decompositions:

41 + 31553021 = 31553062
179 + 31552883 = 31553062
353 + 31552709 = 31553062
419 + 31552643 = 31553062
509 + 31552553 = 31553062
641 + 31552421 = 31553062
659 + 31552403 = 31553062
809 + 31552253 = 31553062

Showing the first eight; more decompositions exist.
