Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496468, here are decompositions:

19 + 31496449 = 31496468
79 + 31496389 = 31496468
97 + 31496371 = 31496468
139 + 31496329 = 31496468
151 + 31496317 = 31496468
307 + 31496161 = 31496468
349 + 31496119 = 31496468
457 + 31496011 = 31496468

Showing the first eight; more decompositions exist.
