Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496866, here are decompositions:

3 + 31496863 = 31496866
47 + 31496819 = 31496866
83 + 31496783 = 31496866
173 + 31496693 = 31496866
197 + 31496669 = 31496866
293 + 31496573 = 31496866
347 + 31496519 = 31496866
449 + 31496417 = 31496866

Showing the first eight; more decompositions exist.
