Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467550, here are decompositions:

11 + 31467539 = 31467550
17 + 31467533 = 31467550
41 + 31467509 = 31467550
47 + 31467503 = 31467550
53 + 31467497 = 31467550
83 + 31467467 = 31467550
113 + 31467437 = 31467550
131 + 31467419 = 31467550

Showing the first eight; more decompositions exist.
