Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593590, here are decompositions:

19 + 31593571 = 31593590
37 + 31593553 = 31593590
73 + 31593517 = 31593590
79 + 31593511 = 31593590
199 + 31593391 = 31593590
277 + 31593313 = 31593590
283 + 31593307 = 31593590
337 + 31593253 = 31593590

Showing the first eight; more decompositions exist.
