Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622646, here are decompositions:

83 + 8622563 = 8622646
173 + 8622473 = 8622646
233 + 8622413 = 8622646
293 + 8622353 = 8622646
353 + 8622293 = 8622646
359 + 8622287 = 8622646
509 + 8622137 = 8622646
719 + 8621927 = 8622646

Showing the first eight; more decompositions exist.
