Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622464, here are decompositions:

3 + 8622461 = 8622464
43 + 8622421 = 8622464
73 + 8622391 = 8622464
127 + 8622337 = 8622464
157 + 8622307 = 8622464
163 + 8622301 = 8622464
223 + 8622241 = 8622464
241 + 8622223 = 8622464

Showing the first eight; more decompositions exist.
