Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702216, here are decompositions:

37 + 8702179 = 8702216
43 + 8702173 = 8702216
67 + 8702149 = 8702216
79 + 8702137 = 8702216
109 + 8702107 = 8702216
283 + 8701933 = 8702216
487 + 8701729 = 8702216
709 + 8701507 = 8702216

Showing the first eight; more decompositions exist.
