Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622388, here are decompositions:

29 + 8622359 = 8622388
101 + 8622287 = 8622388
179 + 8622209 = 8622388
197 + 8622191 = 8622388
251 + 8622137 = 8622388
317 + 8622071 = 8622388
347 + 8622041 = 8622388
449 + 8621939 = 8622388

Showing the first eight; more decompositions exist.
