Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620684, here are decompositions:

11 + 8620673 = 8620684
47 + 8620637 = 8620684
53 + 8620631 = 8620684
113 + 8620571 = 8620684
131 + 8620553 = 8620684
467 + 8620217 = 8620684
563 + 8620121 = 8620684
641 + 8620043 = 8620684

Showing the first eight; more decompositions exist.
