Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455056, here are decompositions:

103 + 31454953 = 31455056
229 + 31454827 = 31455056
673 + 31454383 = 31455056
859 + 31454197 = 31455056
907 + 31454149 = 31455056
1033 + 31454023 = 31455056
1063 + 31453993 = 31455056
1087 + 31453969 = 31455056

Showing the first eight; more decompositions exist.
