Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496894, here are decompositions:

31 + 31496863 = 31496894
67 + 31496827 = 31496894
103 + 31496791 = 31496894
223 + 31496671 = 31496894
283 + 31496611 = 31496894
307 + 31496587 = 31496894
523 + 31496371 = 31496894
577 + 31496317 = 31496894

Showing the first eight; more decompositions exist.
