Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641254, here are decompositions:

5 + 8641249 = 8641254
7 + 8641247 = 8641254
23 + 8641231 = 8641254
43 + 8641211 = 8641254
67 + 8641187 = 8641254
107 + 8641147 = 8641254
157 + 8641097 = 8641254
191 + 8641063 = 8641254

Showing the first eight; more decompositions exist.
