Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681718, here are decompositions:

11 + 8681707 = 8681718
79 + 8681639 = 8681718
131 + 8681587 = 8681718
139 + 8681579 = 8681718
151 + 8681567 = 8681718
179 + 8681539 = 8681718
211 + 8681507 = 8681718
229 + 8681489 = 8681718

Showing the first eight; more decompositions exist.
