Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534016, here are decompositions:

37 + 31533979 = 31534016
67 + 31533949 = 31534016
97 + 31533919 = 31534016
193 + 31533823 = 31534016
379 + 31533637 = 31534016
499 + 31533517 = 31534016
607 + 31533409 = 31534016
673 + 31533343 = 31534016

Showing the first eight; more decompositions exist.
