Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516984, here are decompositions:

3 + 31516981 = 31516984
11 + 31516973 = 31516984
173 + 31516811 = 31516984
197 + 31516787 = 31516984
227 + 31516757 = 31516984
281 + 31516703 = 31516984
353 + 31516631 = 31516984
461 + 31516523 = 31516984

Showing the first eight; more decompositions exist.
