Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496828, here are decompositions:

19 + 31496809 = 31496828
37 + 31496791 = 31496828
109 + 31496719 = 31496828
151 + 31496677 = 31496828
157 + 31496671 = 31496828
229 + 31496599 = 31496828
241 + 31496587 = 31496828
277 + 31496551 = 31496828

Showing the first eight; more decompositions exist.
