Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751218, here are decompositions:

37 + 8751181 = 8751218
61 + 8751157 = 8751218
67 + 8751151 = 8751218
79 + 8751139 = 8751218
127 + 8751091 = 8751218
139 + 8751079 = 8751218
181 + 8751037 = 8751218
211 + 8751007 = 8751218

Showing the first eight; more decompositions exist.
