Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496794, here are decompositions:

3 + 31496791 = 31496794
11 + 31496783 = 31496794
53 + 31496741 = 31496794
101 + 31496693 = 31496794
227 + 31496567 = 31496794
257 + 31496537 = 31496794
353 + 31496441 = 31496794
653 + 31496141 = 31496794

Showing the first eight; more decompositions exist.
