Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554110, here are decompositions:

37 + 31554073 = 31554110
67 + 31554043 = 31554110
97 + 31554013 = 31554110
127 + 31553983 = 31554110
277 + 31553833 = 31554110
307 + 31553803 = 31554110
349 + 31553761 = 31554110
439 + 31553671 = 31554110

Showing the first eight; more decompositions exist.
