Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677218, here are decompositions:

37 + 8677181 = 8677218
47 + 8677171 = 8677218
79 + 8677139 = 8677218
97 + 8677121 = 8677218
139 + 8677079 = 8677218
167 + 8677051 = 8677218
181 + 8677037 = 8677218
191 + 8677027 = 8677218

Showing the first eight; more decompositions exist.
