Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593844, here are decompositions:

5 + 31593839 = 31593844
11 + 31593833 = 31593844
47 + 31593797 = 31593844
197 + 31593647 = 31593844
281 + 31593563 = 31593844
311 + 31593533 = 31593844
353 + 31593491 = 31593844
383 + 31593461 = 31593844

Showing the first eight; more decompositions exist.
