Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593650, here are decompositions:

3 + 31593647 = 31593650
7 + 31593643 = 31593650
19 + 31593631 = 31593650
37 + 31593613 = 31593650
43 + 31593607 = 31593650
61 + 31593589 = 31593650
79 + 31593571 = 31593650
97 + 31593553 = 31593650

Showing the first eight; more decompositions exist.
