Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496882, here are decompositions:

19 + 31496863 = 31496882
73 + 31496809 = 31496882
103 + 31496779 = 31496882
163 + 31496719 = 31496882
211 + 31496671 = 31496882
271 + 31496611 = 31496882
283 + 31496599 = 31496882
331 + 31496551 = 31496882

Showing the first eight; more decompositions exist.
