Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606516, here are decompositions:

17 + 31606499 = 31606516
23 + 31606493 = 31606516
47 + 31606469 = 31606516
173 + 31606343 = 31606516
197 + 31606319 = 31606516
233 + 31606283 = 31606516
239 + 31606277 = 31606516
419 + 31606097 = 31606516

Showing the first eight; more decompositions exist.
