Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706280, here are decompositions:

3 + 8706277 = 8706280
29 + 8706251 = 8706280
41 + 8706239 = 8706280
59 + 8706221 = 8706280
83 + 8706197 = 8706280
131 + 8706149 = 8706280
173 + 8706107 = 8706280
179 + 8706101 = 8706280

Showing the first eight; more decompositions exist.
