Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548016, here are decompositions:

23 + 31547993 = 31548016
83 + 31547933 = 31548016
167 + 31547849 = 31548016
179 + 31547837 = 31548016
233 + 31547783 = 31548016
509 + 31547507 = 31548016
557 + 31547459 = 31548016
659 + 31547357 = 31548016

Showing the first eight; more decompositions exist.
