Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697290, here are decompositions:

13 + 8697277 = 8697290
37 + 8697253 = 8697290
127 + 8697163 = 8697290
157 + 8697133 = 8697290
163 + 8697127 = 8697290
193 + 8697097 = 8697290
229 + 8697061 = 8697290
241 + 8697049 = 8697290

Showing the first eight; more decompositions exist.
