Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568696, here are decompositions:

67 + 31568629 = 31568696
109 + 31568587 = 31568696
157 + 31568539 = 31568696
199 + 31568497 = 31568696
277 + 31568419 = 31568696
283 + 31568413 = 31568696
349 + 31568347 = 31568696
409 + 31568287 = 31568696

Showing the first eight; more decompositions exist.
