Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494896, here are decompositions:

79 + 31494817 = 31494896
127 + 31494769 = 31494896
313 + 31494583 = 31494896
457 + 31494439 = 31494896
739 + 31494157 = 31494896
907 + 31493989 = 31494896
997 + 31493899 = 31494896
1039 + 31493857 = 31494896

Showing the first eight; more decompositions exist.
