Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641958, here are decompositions:

67 + 8641891 = 8641958
139 + 8641819 = 8641958
151 + 8641807 = 8641958
211 + 8641747 = 8641958
307 + 8641651 = 8641958
337 + 8641621 = 8641958
439 + 8641519 = 8641958
487 + 8641471 = 8641958

Showing the first eight; more decompositions exist.
