Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673220, here are decompositions:

11 + 8673209 = 8673220
53 + 8673167 = 8673220
89 + 8673131 = 8673220
107 + 8673113 = 8673220
113 + 8673107 = 8673220
191 + 8673029 = 8673220
251 + 8672969 = 8673220
293 + 8672927 = 8673220

Showing the first eight; more decompositions exist.
