Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467546, here are decompositions:

7 + 31467539 = 31467546
13 + 31467533 = 31467546
37 + 31467509 = 31467546
43 + 31467503 = 31467546
79 + 31467467 = 31467546
109 + 31467437 = 31467546
113 + 31467433 = 31467546
127 + 31467419 = 31467546

Showing the first eight; more decompositions exist.
