Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657198, here are decompositions:

37 + 8657161 = 8657198
157 + 8657041 = 8657198
181 + 8657017 = 8657198
307 + 8656891 = 8657198
349 + 8656849 = 8657198
367 + 8656831 = 8657198
397 + 8656801 = 8657198
439 + 8656759 = 8657198

Showing the first eight; more decompositions exist.
