Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568534, here are decompositions:

7 + 31568527 = 31568534
37 + 31568497 = 31568534
43 + 31568491 = 31568534
181 + 31568353 = 31568534
223 + 31568311 = 31568534
307 + 31568227 = 31568534
313 + 31568221 = 31568534
331 + 31568203 = 31568534

Showing the first eight; more decompositions exist.
