Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85930, here are decompositions:

41 + 85889 = 85930
83 + 85847 = 85930
101 + 85829 = 85930
113 + 85817 = 85930
137 + 85793 = 85930
149 + 85781 = 85930
179 + 85751 = 85930
197 + 85733 = 85930

Showing the first eight; more decompositions exist.
