Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641234, here are decompositions:

3 + 8641231 = 8641234
23 + 8641211 = 8641234
47 + 8641187 = 8641234
101 + 8641133 = 8641234
137 + 8641097 = 8641234
227 + 8641007 = 8641234
257 + 8640977 = 8641234
347 + 8640887 = 8641234

Showing the first eight; more decompositions exist.
