Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606564, here are decompositions:

5 + 31606559 = 31606564
23 + 31606541 = 31606564
47 + 31606517 = 31606564
71 + 31606493 = 31606564
167 + 31606397 = 31606564
191 + 31606373 = 31606564
233 + 31606331 = 31606564
251 + 31606313 = 31606564

Showing the first eight; more decompositions exist.
