Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644460, here are decompositions:

3 + 8644457 = 8644460
7 + 8644453 = 8644460
199 + 8644261 = 8644460
229 + 8644231 = 8644460
313 + 8644147 = 8644460
337 + 8644123 = 8644460
379 + 8644081 = 8644460
463 + 8643997 = 8644460

Showing the first eight; more decompositions exist.
