Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460566, here are decompositions:

17 + 31460549 = 31460566
29 + 31460537 = 31460566
83 + 31460483 = 31460566
167 + 31460399 = 31460566
197 + 31460369 = 31460566
227 + 31460339 = 31460566
503 + 31460063 = 31460566
617 + 31459949 = 31460566

Showing the first eight; more decompositions exist.
