Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707530, here are decompositions:

53 + 8707477 = 8707530
101 + 8707429 = 8707530
109 + 8707421 = 8707530
137 + 8707393 = 8707530
151 + 8707379 = 8707530
173 + 8707357 = 8707530
179 + 8707351 = 8707530
197 + 8707333 = 8707530

Showing the first eight; more decompositions exist.
