Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699390, here are decompositions:

3 + 8699387 = 8699390
79 + 8699311 = 8699390
97 + 8699293 = 8699390
127 + 8699263 = 8699390
151 + 8699239 = 8699390
157 + 8699233 = 8699390
163 + 8699227 = 8699390
211 + 8699179 = 8699390

Showing the first eight; more decompositions exist.
