Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715558, here are decompositions:

107 + 8715451 = 8715558
109 + 8715449 = 8715558
127 + 8715431 = 8715558
149 + 8715409 = 8715558
157 + 8715401 = 8715558
197 + 8715361 = 8715558
211 + 8715347 = 8715558
349 + 8715209 = 8715558

Showing the first eight; more decompositions exist.
