Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606576, here are decompositions:

17 + 31606559 = 31606576
47 + 31606529 = 31606576
59 + 31606517 = 31606576
83 + 31606493 = 31606576
107 + 31606469 = 31606576
179 + 31606397 = 31606576
233 + 31606343 = 31606576
257 + 31606319 = 31606576

Showing the first eight; more decompositions exist.
