Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486676, here are decompositions:

19 + 31486657 = 31486676
37 + 31486639 = 31486676
43 + 31486633 = 31486676
73 + 31486603 = 31486676
127 + 31486549 = 31486676
139 + 31486537 = 31486676
223 + 31486453 = 31486676
283 + 31486393 = 31486676

Showing the first eight; more decompositions exist.
