Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585962, here are decompositions:

59 + 31585903 = 31585962
73 + 31585889 = 31585962
113 + 31585849 = 31585962
139 + 31585823 = 31585962
151 + 31585811 = 31585962
179 + 31585783 = 31585962
181 + 31585781 = 31585962
211 + 31585751 = 31585962

Showing the first eight; more decompositions exist.
