Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599482, here are decompositions:

43 + 31599439 = 31599482
223 + 31599259 = 31599482
379 + 31599103 = 31599482
571 + 31598911 = 31599482
619 + 31598863 = 31599482
643 + 31598839 = 31599482
1033 + 31598449 = 31599482
1063 + 31598419 = 31599482

Showing the first eight; more decompositions exist.
