Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481696, here are decompositions:

13 + 31481683 = 31481696
19 + 31481677 = 31481696
73 + 31481623 = 31481696
199 + 31481497 = 31481696
223 + 31481473 = 31481696
277 + 31481419 = 31481696
307 + 31481389 = 31481696
313 + 31481383 = 31481696

Showing the first eight; more decompositions exist.
