Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642736, here are decompositions:

13 + 8642723 = 8642736
103 + 8642633 = 8642736
227 + 8642509 = 8642736
229 + 8642507 = 8642736
269 + 8642467 = 8642736
283 + 8642453 = 8642736
307 + 8642429 = 8642736
353 + 8642383 = 8642736

Showing the first eight; more decompositions exist.
