Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554116, here are decompositions:

43 + 31554073 = 31554116
73 + 31554043 = 31554116
103 + 31554013 = 31554116
283 + 31553833 = 31554116
313 + 31553803 = 31554116
397 + 31553719 = 31554116
409 + 31553707 = 31554116
457 + 31553659 = 31554116

Showing the first eight; more decompositions exist.
