Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560066, here are decompositions:

7 + 31560059 = 31560066
19 + 31560047 = 31560066
37 + 31560029 = 31560066
47 + 31560019 = 31560066
89 + 31559977 = 31560066
233 + 31559833 = 31560066
257 + 31559809 = 31560066
283 + 31559783 = 31560066

Showing the first eight; more decompositions exist.
