Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560058, here are decompositions:

11 + 31560047 = 31560058
29 + 31560029 = 31560058
107 + 31559951 = 31560058
197 + 31559861 = 31560058
227 + 31559831 = 31560058
281 + 31559777 = 31560058
359 + 31559699 = 31560058
419 + 31559639 = 31560058

Showing the first eight; more decompositions exist.
