Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607218, here are decompositions:

79 + 8607139 = 8607218
157 + 8607061 = 8607218
307 + 8606911 = 8607218
349 + 8606869 = 8607218
379 + 8606839 = 8607218
421 + 8606797 = 8607218
439 + 8606779 = 8607218
619 + 8606599 = 8607218

Showing the first eight; more decompositions exist.
