Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684430, here are decompositions:

11 + 8684419 = 8684430
19 + 8684411 = 8684430
23 + 8684407 = 8684430
71 + 8684359 = 8684430
89 + 8684341 = 8684430
101 + 8684329 = 8684430
151 + 8684279 = 8684430
163 + 8684267 = 8684430

Showing the first eight; more decompositions exist.
