Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593644, here are decompositions:

3 + 31593641 = 31593644
13 + 31593631 = 31593644
31 + 31593613 = 31593644
37 + 31593607 = 31593644
73 + 31593571 = 31593644
127 + 31593517 = 31593644
331 + 31593313 = 31593644
337 + 31593307 = 31593644

Showing the first eight; more decompositions exist.
