Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467568, here are decompositions:

17 + 31467551 = 31467568
29 + 31467539 = 31467568
59 + 31467509 = 31467568
71 + 31467497 = 31467568
101 + 31467467 = 31467568
131 + 31467437 = 31467568
137 + 31467431 = 31467568
149 + 31467419 = 31467568

Showing the first eight; more decompositions exist.
