Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476118, here are decompositions:

5 + 31476113 = 31476118
59 + 31476059 = 31476118
101 + 31476017 = 31476118
269 + 31475849 = 31476118
347 + 31475771 = 31476118
449 + 31475669 = 31476118
521 + 31475597 = 31476118
647 + 31475471 = 31476118

Showing the first eight; more decompositions exist.
