Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467604, here are decompositions:

11 + 31467593 = 31467604
17 + 31467587 = 31467604
53 + 31467551 = 31467604
71 + 31467533 = 31467604
101 + 31467503 = 31467604
107 + 31467497 = 31467604
137 + 31467467 = 31467604
167 + 31467437 = 31467604

Showing the first eight; more decompositions exist.
