Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717180, here are decompositions:

61 + 8717119 = 8717180
67 + 8717113 = 8717180
139 + 8717041 = 8717180
181 + 8716999 = 8717180
223 + 8716957 = 8717180
337 + 8716843 = 8717180
397 + 8716783 = 8717180
421 + 8716759 = 8717180

Showing the first eight; more decompositions exist.
