Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688170, here are decompositions:

3 + 8688167 = 8688170
13 + 8688157 = 8688170
37 + 8688133 = 8688170
61 + 8688109 = 8688170
103 + 8688067 = 8688170
157 + 8688013 = 8688170
241 + 8687929 = 8688170
373 + 8687797 = 8688170

Showing the first eight; more decompositions exist.
