Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496810, here are decompositions:

19 + 31496791 = 31496810
31 + 31496779 = 31496810
139 + 31496671 = 31496810
199 + 31496611 = 31496810
211 + 31496599 = 31496810
223 + 31496587 = 31496810
271 + 31496539 = 31496810
421 + 31496389 = 31496810

Showing the first eight; more decompositions exist.
