Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702220, here are decompositions:

13 + 8702207 = 8702220
31 + 8702189 = 8702220
41 + 8702179 = 8702220
47 + 8702173 = 8702220
61 + 8702159 = 8702220
71 + 8702149 = 8702220
83 + 8702137 = 8702220
89 + 8702131 = 8702220

Showing the first eight; more decompositions exist.
