Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641694, here are decompositions:

43 + 8641651 = 8641694
73 + 8641621 = 8641694
151 + 8641543 = 8641694
181 + 8641513 = 8641694
223 + 8641471 = 8641694
241 + 8641453 = 8641694
367 + 8641327 = 8641694
421 + 8641273 = 8641694

Showing the first eight; more decompositions exist.
