Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642670, here are decompositions:

19 + 8642651 = 8642670
37 + 8642633 = 8642670
79 + 8642591 = 8642670
89 + 8642581 = 8642670
103 + 8642567 = 8642670
137 + 8642533 = 8642670
151 + 8642519 = 8642670
163 + 8642507 = 8642670

Showing the first eight; more decompositions exist.
