Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496736, here are decompositions:

17 + 31496719 = 31496736
43 + 31496693 = 31496736
59 + 31496677 = 31496736
67 + 31496669 = 31496736
137 + 31496599 = 31496736
149 + 31496587 = 31496736
163 + 31496573 = 31496736
197 + 31496539 = 31496736

Showing the first eight; more decompositions exist.
