Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702242, here are decompositions:

11 + 8702231 = 8702242
53 + 8702189 = 8702242
83 + 8702159 = 8702242
149 + 8702093 = 8702242
179 + 8702063 = 8702242
191 + 8702051 = 8702242
233 + 8702009 = 8702242
251 + 8701991 = 8702242

Showing the first eight; more decompositions exist.
