Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697390, here are decompositions:

11 + 8697379 = 8697390
47 + 8697343 = 8697390
89 + 8697301 = 8697390
113 + 8697277 = 8697390
127 + 8697263 = 8697390
137 + 8697253 = 8697390
151 + 8697239 = 8697390
157 + 8697233 = 8697390

Showing the first eight; more decompositions exist.
