Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593692, here are decompositions:

3 + 31593689 = 31593692
61 + 31593631 = 31593692
79 + 31593613 = 31593692
103 + 31593589 = 31593692
139 + 31593553 = 31593692
181 + 31593511 = 31593692
349 + 31593343 = 31593692
379 + 31593313 = 31593692

Showing the first eight; more decompositions exist.
