Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481336, here are decompositions:

37 + 31481299 = 31481336
43 + 31481293 = 31481336
97 + 31481239 = 31481336
157 + 31481179 = 31481336
193 + 31481143 = 31481336
223 + 31481113 = 31481336
373 + 31480963 = 31481336
457 + 31480879 = 31481336

Showing the first eight; more decompositions exist.
