Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554368, here are decompositions:

7 + 31554361 = 31554368
31 + 31554337 = 31554368
127 + 31554241 = 31554368
607 + 31553761 = 31554368
661 + 31553707 = 31554368
709 + 31553659 = 31554368
751 + 31553617 = 31554368
1009 + 31553359 = 31554368

Showing the first eight; more decompositions exist.
