Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467526, here are decompositions:

17 + 31467509 = 31467526
23 + 31467503 = 31467526
29 + 31467497 = 31467526
59 + 31467467 = 31467526
89 + 31467437 = 31467526
107 + 31467419 = 31467526
137 + 31467389 = 31467526
179 + 31467347 = 31467526

Showing the first eight; more decompositions exist.
