Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593836, here are decompositions:

3 + 31593833 = 31593836
73 + 31593763 = 31593836
193 + 31593643 = 31593836
223 + 31593613 = 31593836
229 + 31593607 = 31593836
283 + 31593553 = 31593836
523 + 31593313 = 31593836
643 + 31593193 = 31593836

Showing the first eight; more decompositions exist.
