Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669290, here are decompositions:

11 + 8669279 = 8669290
41 + 8669249 = 8669290
53 + 8669237 = 8669290
83 + 8669207 = 8669290
101 + 8669189 = 8669290
131 + 8669159 = 8669290
167 + 8669123 = 8669290
173 + 8669117 = 8669290

Showing the first eight; more decompositions exist.
