Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565926, here are decompositions:

233 + 31565693 = 31565926
263 + 31565663 = 31565926
503 + 31565423 = 31565926
617 + 31565309 = 31565926
647 + 31565279 = 31565926
677 + 31565249 = 31565926
719 + 31565207 = 31565926
797 + 31565129 = 31565926

Showing the first eight; more decompositions exist.
