Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702290, here are decompositions:

11 + 8702279 = 8702290
59 + 8702231 = 8702290
83 + 8702207 = 8702290
101 + 8702189 = 8702290
131 + 8702159 = 8702290
197 + 8702093 = 8702290
227 + 8702063 = 8702290
239 + 8702051 = 8702290

Showing the first eight; more decompositions exist.
