Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467850, here are decompositions:

3 + 31467847 = 31467850
41 + 31467809 = 31467850
83 + 31467767 = 31467850
131 + 31467719 = 31467850
173 + 31467677 = 31467850
257 + 31467593 = 31467850
263 + 31467587 = 31467850
311 + 31467539 = 31467850

Showing the first eight; more decompositions exist.
