Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496876, here are decompositions:

3 + 31496873 = 31496876
13 + 31496863 = 31496876
67 + 31496809 = 31496876
97 + 31496779 = 31496876
157 + 31496719 = 31496876
199 + 31496677 = 31496876
277 + 31496599 = 31496876
283 + 31496593 = 31496876

Showing the first eight; more decompositions exist.
