Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467522, here are decompositions:

13 + 31467509 = 31467522
19 + 31467503 = 31467522
41 + 31467481 = 31467522
89 + 31467433 = 31467522
103 + 31467419 = 31467522
193 + 31467329 = 31467522
211 + 31467311 = 31467522
263 + 31467259 = 31467522

Showing the first eight; more decompositions exist.
