Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560010, here are decompositions:

29 + 31559981 = 31560010
59 + 31559951 = 31560010
149 + 31559861 = 31560010
179 + 31559831 = 31560010
197 + 31559813 = 31560010
227 + 31559783 = 31560010
233 + 31559777 = 31560010
239 + 31559771 = 31560010

Showing the first eight; more decompositions exist.
