Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476850, here are decompositions:

3 + 31476847 = 31476850
29 + 31476821 = 31476850
107 + 31476743 = 31476850
227 + 31476623 = 31476850
239 + 31476611 = 31476850
257 + 31476593 = 31476850
263 + 31476587 = 31476850
389 + 31476461 = 31476850

Showing the first eight; more decompositions exist.
