Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560062, here are decompositions:

3 + 31560059 = 31560062
43 + 31560019 = 31560062
73 + 31559989 = 31560062
151 + 31559911 = 31560062
211 + 31559851 = 31560062
229 + 31559833 = 31560062
241 + 31559821 = 31560062
409 + 31559653 = 31560062

Showing the first eight; more decompositions exist.
