Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671430, here are decompositions:

3 + 8671427 = 8671430
37 + 8671393 = 8671430
67 + 8671363 = 8671430
109 + 8671321 = 8671430
139 + 8671291 = 8671430
181 + 8671249 = 8671430
199 + 8671231 = 8671430
211 + 8671219 = 8671430

Showing the first eight; more decompositions exist.
