Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564006, here are decompositions:

17 + 31563989 = 31564006
53 + 31563953 = 31564006
59 + 31563947 = 31564006
107 + 31563899 = 31564006
179 + 31563827 = 31564006
233 + 31563773 = 31564006
269 + 31563737 = 31564006
359 + 31563647 = 31564006

Showing the first eight; more decompositions exist.
