Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476244, here are decompositions:

5 + 31476239 = 31476244
101 + 31476143 = 31476244
131 + 31476113 = 31476244
227 + 31476017 = 31476244
281 + 31475963 = 31476244
431 + 31475813 = 31476244
467 + 31475777 = 31476244
563 + 31475681 = 31476244

Showing the first eight; more decompositions exist.
