Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702670, here are decompositions:

7 + 8702663 = 8702670
23 + 8702647 = 8702670
73 + 8702597 = 8702670
79 + 8702591 = 8702670
83 + 8702587 = 8702670
101 + 8702569 = 8702670
113 + 8702557 = 8702670
127 + 8702543 = 8702670

Showing the first eight; more decompositions exist.
