Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688218, here are decompositions:

61 + 8688157 = 8688218
109 + 8688109 = 8688218
151 + 8688067 = 8688218
307 + 8687911 = 8688218
337 + 8687881 = 8688218
421 + 8687797 = 8688218
547 + 8687671 = 8688218
577 + 8687641 = 8688218

Showing the first eight; more decompositions exist.
