Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476968, here are decompositions:

37 + 31476931 = 31476968
97 + 31476871 = 31476968
139 + 31476829 = 31476968
241 + 31476727 = 31476968
277 + 31476691 = 31476968
337 + 31476631 = 31476968
421 + 31476547 = 31476968
577 + 31476391 = 31476968

Showing the first eight; more decompositions exist.
