Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593746, here are decompositions:

43 + 31593703 = 31593746
103 + 31593643 = 31593746
139 + 31593607 = 31593746
157 + 31593589 = 31593746
193 + 31593553 = 31593746
229 + 31593517 = 31593746
433 + 31593313 = 31593746
439 + 31593307 = 31593746

Showing the first eight; more decompositions exist.
