Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684380, here are decompositions:

101 + 8684279 = 8684380
113 + 8684267 = 8684380
137 + 8684243 = 8684380
149 + 8684231 = 8684380
167 + 8684213 = 8684380
179 + 8684201 = 8684380
191 + 8684189 = 8684380
233 + 8684147 = 8684380

Showing the first eight; more decompositions exist.
