Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496996, here are decompositions:

7 + 31496989 = 31496996
19 + 31496977 = 31496996
79 + 31496917 = 31496996
277 + 31496719 = 31496996
397 + 31496599 = 31496996
409 + 31496587 = 31496996
457 + 31496539 = 31496996
547 + 31496449 = 31496996

Showing the first eight; more decompositions exist.
