Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706218, here are decompositions:

139 + 8706079 = 8706218
211 + 8706007 = 8706218
277 + 8705941 = 8706218
307 + 8705911 = 8706218
337 + 8705881 = 8706218
601 + 8705617 = 8706218
607 + 8705611 = 8706218
691 + 8705527 = 8706218

Showing the first eight; more decompositions exist.
