Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496814, here are decompositions:

5 + 31496809 = 31496814
23 + 31496791 = 31496814
31 + 31496783 = 31496814
73 + 31496741 = 31496814
137 + 31496677 = 31496814
227 + 31496587 = 31496814
241 + 31496573 = 31496814
263 + 31496551 = 31496814

Showing the first eight; more decompositions exist.
