Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658550, here are decompositions:

23 + 8658527 = 8658550
137 + 8658413 = 8658550
167 + 8658383 = 8658550
179 + 8658371 = 8658550
227 + 8658323 = 8658550
317 + 8658233 = 8658550
347 + 8658203 = 8658550
389 + 8658161 = 8658550

Showing the first eight; more decompositions exist.
