Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481036, here are decompositions:

73 + 31480963 = 31481036
157 + 31480879 = 31481036
163 + 31480873 = 31481036
397 + 31480639 = 31481036
907 + 31480129 = 31481036
919 + 31480117 = 31481036
1087 + 31479949 = 31481036
1279 + 31479757 = 31481036

Showing the first eight; more decompositions exist.
