Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669788, here are decompositions:

11 + 8669777 = 8669788
131 + 8669657 = 8669788
137 + 8669651 = 8669788
167 + 8669621 = 8669788
311 + 8669477 = 8669788
389 + 8669399 = 8669788
509 + 8669279 = 8669788
599 + 8669189 = 8669788

Showing the first eight; more decompositions exist.
