Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496864, here are decompositions:

37 + 31496827 = 31496864
73 + 31496791 = 31496864
193 + 31496671 = 31496864
271 + 31496593 = 31496864
277 + 31496587 = 31496864
313 + 31496551 = 31496864
547 + 31496317 = 31496864
571 + 31496293 = 31496864

Showing the first eight; more decompositions exist.
