Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606584, here are decompositions:

5 + 31606579 = 31606584
41 + 31606543 = 31606584
43 + 31606541 = 31606584
47 + 31606537 = 31606584
67 + 31606517 = 31606584
173 + 31606411 = 31606584
197 + 31606387 = 31606584
211 + 31606373 = 31606584

Showing the first eight; more decompositions exist.
