Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8682420, here are decompositions:

7 + 8682413 = 8682420
11 + 8682409 = 8682420
17 + 8682403 = 8682420
29 + 8682391 = 8682420
101 + 8682319 = 8682420
151 + 8682269 = 8682420
167 + 8682253 = 8682420
179 + 8682241 = 8682420

Showing the first eight; more decompositions exist.
