Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554008, here are decompositions:

337 + 31553671 = 31554008
349 + 31553659 = 31554008
919 + 31553089 = 31554008
991 + 31553017 = 31554008
1009 + 31552999 = 31554008
1117 + 31552891 = 31554008
1129 + 31552879 = 31554008
1327 + 31552681 = 31554008

Showing the first eight; more decompositions exist.
