Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622748, here are decompositions:

41 + 8622707 = 8622748
137 + 8622611 = 8622748
227 + 8622521 = 8622748
257 + 8622491 = 8622748
389 + 8622359 = 8622748
461 + 8622287 = 8622748
557 + 8622191 = 8622748
677 + 8622071 = 8622748

Showing the first eight; more decompositions exist.
