Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496966, here are decompositions:

3 + 31496963 = 31496966
19 + 31496947 = 31496966
103 + 31496863 = 31496966
139 + 31496827 = 31496966
157 + 31496809 = 31496966
367 + 31496599 = 31496966
373 + 31496593 = 31496966
379 + 31496587 = 31496966

Showing the first eight; more decompositions exist.
