Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719670, here are decompositions:

7 + 8719663 = 8719670
67 + 8719603 = 8719670
79 + 8719591 = 8719670
97 + 8719573 = 8719670
103 + 8719567 = 8719670
151 + 8719519 = 8719670
229 + 8719441 = 8719670
367 + 8719303 = 8719670

Showing the first eight; more decompositions exist.
