Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654480, here are decompositions:

13 + 8654467 = 8654480
19 + 8654461 = 8654480
181 + 8654299 = 8654480
193 + 8654287 = 8654480
199 + 8654281 = 8654480
223 + 8654257 = 8654480
433 + 8654047 = 8654480
463 + 8654017 = 8654480

Showing the first eight; more decompositions exist.
