Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707028, here are decompositions:

7 + 8707021 = 8707028
61 + 8706967 = 8707028
67 + 8706961 = 8707028
157 + 8706871 = 8707028
199 + 8706829 = 8707028
277 + 8706751 = 8707028
571 + 8706457 = 8707028
661 + 8706367 = 8707028

Showing the first eight; more decompositions exist.
