Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448266, here are decompositions:

197 + 31448069 = 31448266
233 + 31448033 = 31448266
467 + 31447799 = 31448266
593 + 31447673 = 31448266
599 + 31447667 = 31448266
659 + 31447607 = 31448266
683 + 31447583 = 31448266
809 + 31447457 = 31448266

Showing the first eight; more decompositions exist.
