Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496694, here are decompositions:

17 + 31496677 = 31496694
23 + 31496671 = 31496694
83 + 31496611 = 31496694
101 + 31496593 = 31496694
107 + 31496587 = 31496694
127 + 31496567 = 31496694
157 + 31496537 = 31496694
277 + 31496417 = 31496694

Showing the first eight; more decompositions exist.
