Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476526, here are decompositions:

17 + 31476509 = 31476526
89 + 31476437 = 31476526
113 + 31476413 = 31476526
173 + 31476353 = 31476526
383 + 31476143 = 31476526
467 + 31476059 = 31476526
509 + 31476017 = 31476526
563 + 31475963 = 31476526

Showing the first eight; more decompositions exist.
