Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618344, here are decompositions:

5 + 8618339 = 8618344
17 + 8618327 = 8618344
47 + 8618297 = 8618344
71 + 8618273 = 8618344
101 + 8618243 = 8618344
107 + 8618237 = 8618344
131 + 8618213 = 8618344
197 + 8618147 = 8618344

Showing the first eight; more decompositions exist.
