Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641924, here are decompositions:

41 + 8641883 = 8641924
107 + 8641817 = 8641924
191 + 8641733 = 8641924
227 + 8641697 = 8641924
251 + 8641673 = 8641924
281 + 8641643 = 8641924
293 + 8641631 = 8641924
311 + 8641613 = 8641924

Showing the first eight; more decompositions exist.
