Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467570, here are decompositions:

11 + 31467559 = 31467570
19 + 31467551 = 31467570
31 + 31467539 = 31467570
37 + 31467533 = 31467570
61 + 31467509 = 31467570
67 + 31467503 = 31467570
73 + 31467497 = 31467570
89 + 31467481 = 31467570

Showing the first eight; more decompositions exist.
