Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519046, here are decompositions:

373 + 31518673 = 31519046
439 + 31518607 = 31519046
457 + 31518589 = 31519046
523 + 31518523 = 31519046
619 + 31518427 = 31519046
733 + 31518313 = 31519046
787 + 31518259 = 31519046
883 + 31518163 = 31519046

Showing the first eight; more decompositions exist.
