Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585022, here are decompositions:

3 + 31585019 = 31585022
61 + 31584961 = 31585022
193 + 31584829 = 31585022
199 + 31584823 = 31585022
409 + 31584613 = 31585022
421 + 31584601 = 31585022
463 + 31584559 = 31585022
499 + 31584523 = 31585022

Showing the first eight; more decompositions exist.
