Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707220, here are decompositions:

13 + 8707207 = 8707220
31 + 8707189 = 8707220
37 + 8707183 = 8707220
61 + 8707159 = 8707220
73 + 8707147 = 8707220
97 + 8707123 = 8707220
127 + 8707093 = 8707220
163 + 8707057 = 8707220

Showing the first eight; more decompositions exist.
