Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700788, here are decompositions:

37 + 8700751 = 8700788
67 + 8700721 = 8700788
79 + 8700709 = 8700788
139 + 8700649 = 8700788
199 + 8700589 = 8700788
241 + 8700547 = 8700788
277 + 8700511 = 8700788
331 + 8700457 = 8700788

Showing the first eight; more decompositions exist.
