Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727618, here are decompositions:

7 + 8727611 = 8727618
17 + 8727601 = 8727618
19 + 8727599 = 8727618
41 + 8727577 = 8727618
79 + 8727539 = 8727618
89 + 8727529 = 8727618
167 + 8727451 = 8727618
191 + 8727427 = 8727618

Showing the first eight; more decompositions exist.
