Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700830, here are decompositions:

3 + 8700827 = 8700830
13 + 8700817 = 8700830
31 + 8700799 = 8700830
37 + 8700793 = 8700830
79 + 8700751 = 8700830
109 + 8700721 = 8700830
181 + 8700649 = 8700830
241 + 8700589 = 8700830

Showing the first eight; more decompositions exist.
