Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467516, here are decompositions:

7 + 31467509 = 31467516
13 + 31467503 = 31467516
19 + 31467497 = 31467516
79 + 31467437 = 31467516
83 + 31467433 = 31467516
97 + 31467419 = 31467516
127 + 31467389 = 31467516
149 + 31467367 = 31467516

Showing the first eight; more decompositions exist.
