Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620648, here are decompositions:

11 + 8620637 = 8620648
17 + 8620631 = 8620648
59 + 8620589 = 8620648
149 + 8620499 = 8620648
359 + 8620289 = 8620648
389 + 8620259 = 8620648
431 + 8620217 = 8620648
461 + 8620187 = 8620648

Showing the first eight; more decompositions exist.
