Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642756, here are decompositions:

223 + 8642533 = 8642756
307 + 8642449 = 8642756
373 + 8642383 = 8642756
769 + 8641987 = 8642756
883 + 8641873 = 8642756
937 + 8641819 = 8642756
1009 + 8641747 = 8642756
1087 + 8641669 = 8642756

Showing the first eight; more decompositions exist.
