Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594202, here are decompositions:

43 + 31594159 = 31594202
139 + 31594063 = 31594202
163 + 31594039 = 31594202
271 + 31593931 = 31594202
439 + 31593763 = 31594202
499 + 31593703 = 31594202
571 + 31593631 = 31594202
613 + 31593589 = 31594202

Showing the first eight; more decompositions exist.
