Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629684, here are decompositions:

3 + 8629681 = 8629684
5 + 8629679 = 8629684
23 + 8629661 = 8629684
47 + 8629637 = 8629684
71 + 8629613 = 8629684
101 + 8629583 = 8629684
251 + 8629433 = 8629684
443 + 8629241 = 8629684

Showing the first eight; more decompositions exist.
