Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645854, here are decompositions:

5 + 8645849 = 8645854
167 + 8645687 = 8645854
197 + 8645657 = 8645854
257 + 8645597 = 8645854
311 + 8645543 = 8645854
587 + 8645267 = 8645854
593 + 8645261 = 8645854
617 + 8645237 = 8645854

Showing the first eight; more decompositions exist.
