Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568594, here are decompositions:

7 + 31568587 = 31568594
67 + 31568527 = 31568594
97 + 31568497 = 31568594
103 + 31568491 = 31568594
181 + 31568413 = 31568594
241 + 31568353 = 31568594
283 + 31568311 = 31568594
307 + 31568287 = 31568594

Showing the first eight; more decompositions exist.
