Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641922, here are decompositions:

13 + 8641909 = 8641922
31 + 8641891 = 8641922
103 + 8641819 = 8641922
139 + 8641783 = 8641922
181 + 8641741 = 8641922
271 + 8641651 = 8641922
379 + 8641543 = 8641922
409 + 8641513 = 8641922

Showing the first eight; more decompositions exist.
