Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467566, here are decompositions:

7 + 31467559 = 31467566
199 + 31467367 = 31467566
307 + 31467259 = 31467566
337 + 31467229 = 31467566
367 + 31467199 = 31467566
397 + 31467169 = 31467566
409 + 31467157 = 31467566
433 + 31467133 = 31467566

Showing the first eight; more decompositions exist.
