Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471466, here are decompositions:

79 + 31471387 = 31471466
109 + 31471357 = 31471466
373 + 31471093 = 31471466
577 + 31470889 = 31471466
613 + 31470853 = 31471466
619 + 31470847 = 31471466
643 + 31470823 = 31471466
673 + 31470793 = 31471466

Showing the first eight; more decompositions exist.
