Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621684, here are decompositions:

3 + 8621681 = 8621684
7 + 8621677 = 8621684
31 + 8621653 = 8621684
61 + 8621623 = 8621684
67 + 8621617 = 8621684
103 + 8621581 = 8621684
193 + 8621491 = 8621684
241 + 8621443 = 8621684

Showing the first eight; more decompositions exist.
