Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712108, here are decompositions:

17 + 8712091 = 8712108
79 + 8712029 = 8712108
89 + 8712019 = 8712108
137 + 8711971 = 8712108
157 + 8711951 = 8712108
211 + 8711897 = 8712108
239 + 8711869 = 8712108
241 + 8711867 = 8712108

Showing the first eight; more decompositions exist.
