Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467556, here are decompositions:

5 + 31467551 = 31467556
17 + 31467539 = 31467556
23 + 31467533 = 31467556
47 + 31467509 = 31467556
53 + 31467503 = 31467556
59 + 31467497 = 31467556
89 + 31467467 = 31467556
137 + 31467419 = 31467556

Showing the first eight; more decompositions exist.
