Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554098, here are decompositions:

337 + 31553761 = 31554098
379 + 31553719 = 31554098
439 + 31553659 = 31554098
571 + 31553527 = 31554098
739 + 31553359 = 31554098
937 + 31553161 = 31554098
1009 + 31553089 = 31554098
1021 + 31553077 = 31554098

Showing the first eight; more decompositions exist.
