Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559962, here are decompositions:

11 + 31559951 = 31559962
101 + 31559861 = 31559962
113 + 31559849 = 31559962
131 + 31559831 = 31559962
149 + 31559813 = 31559962
179 + 31559783 = 31559962
191 + 31559771 = 31559962
263 + 31559699 = 31559962

Showing the first eight; more decompositions exist.
