Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671670, here are decompositions:

31 + 8671639 = 8671670
37 + 8671633 = 8671670
97 + 8671573 = 8671670
151 + 8671519 = 8671670
199 + 8671471 = 8671670
223 + 8671447 = 8671670
229 + 8671441 = 8671670
277 + 8671393 = 8671670

Showing the first eight; more decompositions exist.
