Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618506, here are decompositions:

5 + 8618501 = 8618506
23 + 8618483 = 8618506
167 + 8618339 = 8618506
179 + 8618327 = 8618506
233 + 8618273 = 8618506
263 + 8618243 = 8618506
269 + 8618237 = 8618506
293 + 8618213 = 8618506

Showing the first eight; more decompositions exist.
