Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689918, here are decompositions:

101 + 8689817 = 8689918
191 + 8689727 = 8689918
257 + 8689661 = 8689918
269 + 8689649 = 8689918
389 + 8689529 = 8689918
467 + 8689451 = 8689918
569 + 8689349 = 8689918
599 + 8689319 = 8689918

Showing the first eight; more decompositions exist.
