Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563848, here are decompositions:

31 + 31563817 = 31563848
61 + 31563787 = 31563848
397 + 31563451 = 31563848
457 + 31563391 = 31563848
499 + 31563349 = 31563848
571 + 31563277 = 31563848
661 + 31563187 = 31563848
937 + 31562911 = 31563848

Showing the first eight; more decompositions exist.
