Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641436, here are decompositions:

3 + 8641433 = 8641436
7 + 8641429 = 8641436
109 + 8641327 = 8641436
127 + 8641309 = 8641436
163 + 8641273 = 8641436
373 + 8641063 = 8641436
487 + 8640949 = 8641436
547 + 8640889 = 8641436

Showing the first eight; more decompositions exist.
