Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663420, here are decompositions:

19 + 8663401 = 8663420
109 + 8663311 = 8663420
211 + 8663209 = 8663420
331 + 8663089 = 8663420
349 + 8663071 = 8663420
397 + 8663023 = 8663420
433 + 8662987 = 8663420
457 + 8662963 = 8663420

Showing the first eight; more decompositions exist.
