Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554332, here are decompositions:

151 + 31554181 = 31554332
211 + 31554121 = 31554332
349 + 31553983 = 31554332
499 + 31553833 = 31554332
571 + 31553761 = 31554332
613 + 31553719 = 31554332
661 + 31553671 = 31554332
673 + 31553659 = 31554332

Showing the first eight; more decompositions exist.
