Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554002, here are decompositions:

19 + 31553983 = 31554002
199 + 31553803 = 31554002
241 + 31553761 = 31554002
283 + 31553719 = 31554002
331 + 31553671 = 31554002
499 + 31553503 = 31554002
619 + 31553383 = 31554002
643 + 31553359 = 31554002

Showing the first eight; more decompositions exist.
