Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628622, here are decompositions:

71 + 8628551 = 8628622
173 + 8628449 = 8628622
179 + 8628443 = 8628622
239 + 8628383 = 8628622
263 + 8628359 = 8628622
269 + 8628353 = 8628622
389 + 8628233 = 8628622
419 + 8628203 = 8628622

Showing the first eight; more decompositions exist.
