Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82878, here are decompositions:

31 + 82847 = 82878
41 + 82837 = 82878
67 + 82811 = 82878
79 + 82799 = 82878
97 + 82781 = 82878
149 + 82729 = 82878
151 + 82727 = 82878
157 + 82721 = 82878

Showing the first eight; more decompositions exist.
