Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496726, here are decompositions:

7 + 31496719 = 31496726
127 + 31496599 = 31496726
139 + 31496587 = 31496726
277 + 31496449 = 31496726
307 + 31496419 = 31496726
337 + 31496389 = 31496726
397 + 31496329 = 31496726
409 + 31496317 = 31496726

Showing the first eight; more decompositions exist.
