Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554462, here are decompositions:

13 + 31554449 = 31554462
29 + 31554433 = 31554462
53 + 31554409 = 31554462
61 + 31554401 = 31554462
101 + 31554361 = 31554462
179 + 31554283 = 31554462
263 + 31554199 = 31554462
281 + 31554181 = 31554462

Showing the first eight; more decompositions exist.
