Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670730, here are decompositions:

17 + 8670713 = 8670730
179 + 8670551 = 8670730
197 + 8670533 = 8670730
227 + 8670503 = 8670730
239 + 8670491 = 8670730
359 + 8670371 = 8670730
449 + 8670281 = 8670730
491 + 8670239 = 8670730

Showing the first eight; more decompositions exist.
