Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593950, here are decompositions:

7 + 31593943 = 31593950
13 + 31593937 = 31593950
19 + 31593931 = 31593950
163 + 31593787 = 31593950
229 + 31593721 = 31593950
307 + 31593643 = 31593950
337 + 31593613 = 31593950
379 + 31593571 = 31593950

Showing the first eight; more decompositions exist.
