Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622628, here are decompositions:

17 + 8622611 = 8622628
107 + 8622521 = 8622628
137 + 8622491 = 8622628
167 + 8622461 = 8622628
269 + 8622359 = 8622628
419 + 8622209 = 8622628
491 + 8622137 = 8622628
557 + 8622071 = 8622628

Showing the first eight; more decompositions exist.
