Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554464, here are decompositions:

31 + 31554433 = 31554464
103 + 31554361 = 31554464
127 + 31554337 = 31554464
181 + 31554283 = 31554464
223 + 31554241 = 31554464
283 + 31554181 = 31554464
421 + 31554043 = 31554464
631 + 31553833 = 31554464

Showing the first eight; more decompositions exist.
