Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496486, here are decompositions:

37 + 31496449 = 31496486
67 + 31496419 = 31496486
97 + 31496389 = 31496486
157 + 31496329 = 31496486
193 + 31496293 = 31496486
223 + 31496263 = 31496486
277 + 31496209 = 31496486
313 + 31496173 = 31496486

Showing the first eight; more decompositions exist.
