Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8682390, here are decompositions:

47 + 8682343 = 8682390
71 + 8682319 = 8682390
113 + 8682277 = 8682390
137 + 8682253 = 8682390
139 + 8682251 = 8682390
149 + 8682241 = 8682390
151 + 8682239 = 8682390
179 + 8682211 = 8682390

Showing the first eight; more decompositions exist.
