Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559934, here are decompositions:

23 + 31559911 = 31559934
73 + 31559861 = 31559934
83 + 31559851 = 31559934
101 + 31559833 = 31559934
103 + 31559831 = 31559934
113 + 31559821 = 31559934
151 + 31559783 = 31559934
157 + 31559777 = 31559934

Showing the first eight; more decompositions exist.
