Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644394, here are decompositions:

67 + 8644327 = 8644394
151 + 8644243 = 8644394
163 + 8644231 = 8644394
181 + 8644213 = 8644394
223 + 8644171 = 8644394
271 + 8644123 = 8644394
313 + 8644081 = 8644394
337 + 8644057 = 8644394

Showing the first eight; more decompositions exist.
