Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496846, here are decompositions:

19 + 31496827 = 31496846
37 + 31496809 = 31496846
67 + 31496779 = 31496846
127 + 31496719 = 31496846
307 + 31496539 = 31496846
397 + 31496449 = 31496846
457 + 31496389 = 31496846
673 + 31496173 = 31496846

Showing the first eight; more decompositions exist.
