Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518926, here are decompositions:

3 + 31518923 = 31518926
13 + 31518913 = 31518926
67 + 31518859 = 31518926
337 + 31518589 = 31518926
499 + 31518427 = 31518926
547 + 31518379 = 31518926
613 + 31518313 = 31518926
787 + 31518139 = 31518926

Showing the first eight; more decompositions exist.
