Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618350, here are decompositions:

11 + 8618339 = 8618350
23 + 8618327 = 8618350
53 + 8618297 = 8618350
107 + 8618243 = 8618350
113 + 8618237 = 8618350
137 + 8618213 = 8618350
263 + 8618087 = 8618350
317 + 8618033 = 8618350

Showing the first eight; more decompositions exist.
