Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684, here are decompositions:

3 + 8681 = 8684
7 + 8677 = 8684
37 + 8647 = 8684
43 + 8641 = 8684
61 + 8623 = 8684
103 + 8581 = 8684
157 + 8527 = 8684
163 + 8521 = 8684

Showing the first eight; more decompositions exist.
