Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554122, here are decompositions:

79 + 31554043 = 31554122
109 + 31554013 = 31554122
139 + 31553983 = 31554122
463 + 31553659 = 31554122
619 + 31553503 = 31554122
739 + 31553383 = 31554122
1033 + 31553089 = 31554122
1123 + 31552999 = 31554122

Showing the first eight; more decompositions exist.
