Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622538, here are decompositions:

17 + 8622521 = 8622538
47 + 8622491 = 8622538
179 + 8622359 = 8622538
251 + 8622287 = 8622538
347 + 8622191 = 8622538
401 + 8622137 = 8622538
467 + 8622071 = 8622538
521 + 8622017 = 8622538

Showing the first eight; more decompositions exist.
