Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467844, here are decompositions:

167 + 31467677 = 31467844
197 + 31467647 = 31467844
251 + 31467593 = 31467844
257 + 31467587 = 31467844
293 + 31467551 = 31467844
311 + 31467533 = 31467844
347 + 31467497 = 31467844
593 + 31467251 = 31467844

Showing the first eight; more decompositions exist.
