Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560060, here are decompositions:

13 + 31560047 = 31560060
31 + 31560029 = 31560060
41 + 31560019 = 31560060
71 + 31559989 = 31560060
79 + 31559981 = 31560060
83 + 31559977 = 31560060
109 + 31559951 = 31560060
149 + 31559911 = 31560060

Showing the first eight; more decompositions exist.
