Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622408, here are decompositions:

17 + 8622391 = 8622408
29 + 8622379 = 8622408
71 + 8622337 = 8622408
101 + 8622307 = 8622408
107 + 8622301 = 8622408
167 + 8622241 = 8622408
199 + 8622209 = 8622408
271 + 8622137 = 8622408

Showing the first eight; more decompositions exist.
