Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467826, here are decompositions:

17 + 31467809 = 31467826
59 + 31467767 = 31467826
107 + 31467719 = 31467826
149 + 31467677 = 31467826
179 + 31467647 = 31467826
233 + 31467593 = 31467826
239 + 31467587 = 31467826
293 + 31467533 = 31467826

Showing the first eight; more decompositions exist.
