Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467772, here are decompositions:

5 + 31467767 = 31467772
53 + 31467719 = 31467772
179 + 31467593 = 31467772
233 + 31467539 = 31467772
239 + 31467533 = 31467772
263 + 31467509 = 31467772
269 + 31467503 = 31467772
353 + 31467419 = 31467772

Showing the first eight; more decompositions exist.
