Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560022, here are decompositions:

3 + 31560019 = 31560022
41 + 31559981 = 31560022
71 + 31559951 = 31560022
173 + 31559849 = 31560022
191 + 31559831 = 31560022
239 + 31559783 = 31560022
251 + 31559771 = 31560022
383 + 31559639 = 31560022

Showing the first eight; more decompositions exist.
