Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593686, here are decompositions:

43 + 31593643 = 31593686
73 + 31593613 = 31593686
79 + 31593607 = 31593686
97 + 31593589 = 31593686
373 + 31593313 = 31593686
379 + 31593307 = 31593686
433 + 31593253 = 31593686
577 + 31593109 = 31593686

Showing the first eight; more decompositions exist.
