Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481276, here are decompositions:

37 + 31481239 = 31481276
97 + 31481179 = 31481276
163 + 31481113 = 31481276
199 + 31481077 = 31481276
313 + 31480963 = 31481276
397 + 31480879 = 31481276
769 + 31480507 = 31481276
907 + 31480369 = 31481276

Showing the first eight; more decompositions exist.
