Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467886, here are decompositions:

167 + 31467719 = 31467886
239 + 31467647 = 31467886
293 + 31467593 = 31467886
347 + 31467539 = 31467886
353 + 31467533 = 31467886
383 + 31467503 = 31467886
389 + 31467497 = 31467886
419 + 31467467 = 31467886

Showing the first eight; more decompositions exist.
