Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641444, here are decompositions:

11 + 8641433 = 8641444
23 + 8641421 = 8641444
83 + 8641361 = 8641444
113 + 8641331 = 8641444
197 + 8641247 = 8641444
233 + 8641211 = 8641444
257 + 8641187 = 8641444
311 + 8641133 = 8641444

Showing the first eight; more decompositions exist.
