Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553798, here are decompositions:

37 + 31553761 = 31553798
79 + 31553719 = 31553798
127 + 31553671 = 31553798
139 + 31553659 = 31553798
181 + 31553617 = 31553798
271 + 31553527 = 31553798
439 + 31553359 = 31553798
709 + 31553089 = 31553798

Showing the first eight; more decompositions exist.
