Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594196, here are decompositions:

3 + 31594193 = 31594196
37 + 31594159 = 31594196
157 + 31594039 = 31594196
409 + 31593787 = 31594196
433 + 31593763 = 31594196
607 + 31593589 = 31594196
643 + 31593553 = 31594196
853 + 31593343 = 31594196

Showing the first eight; more decompositions exist.
