Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641456, here are decompositions:

3 + 8641453 = 8641456
23 + 8641433 = 8641456
107 + 8641349 = 8641456
137 + 8641319 = 8641456
167 + 8641289 = 8641456
269 + 8641187 = 8641456
359 + 8641097 = 8641456
449 + 8641007 = 8641456

Showing the first eight; more decompositions exist.
