Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554326, here are decompositions:

43 + 31554283 = 31554326
127 + 31554199 = 31554326
163 + 31554163 = 31554326
283 + 31554043 = 31554326
313 + 31554013 = 31554326
523 + 31553803 = 31554326
607 + 31553719 = 31554326
619 + 31553707 = 31554326

Showing the first eight; more decompositions exist.
