Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82864, here are decompositions:

17 + 82847 = 82864
53 + 82811 = 82864
71 + 82793 = 82864
83 + 82781 = 82864
101 + 82763 = 82864
107 + 82757 = 82864
137 + 82727 = 82864
251 + 82613 = 82864

Showing the first eight; more decompositions exist.
