Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660670, here are decompositions:

13 + 8660657 = 8660670
17 + 8660653 = 8660670
47 + 8660623 = 8660670
59 + 8660611 = 8660670
61 + 8660609 = 8660670
101 + 8660569 = 8660670
127 + 8660543 = 8660670
131 + 8660539 = 8660670

Showing the first eight; more decompositions exist.
