Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563926, here are decompositions:

19 + 31563907 = 31563926
109 + 31563817 = 31563926
139 + 31563787 = 31563926
193 + 31563733 = 31563926
463 + 31563463 = 31563926
523 + 31563403 = 31563926
577 + 31563349 = 31563926
643 + 31563283 = 31563926

Showing the first eight; more decompositions exist.
