Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663218, here are decompositions:

101 + 8663117 = 8663218
227 + 8662991 = 8663218
359 + 8662859 = 8663218
419 + 8662799 = 8663218
449 + 8662769 = 8663218
467 + 8662751 = 8663218
569 + 8662649 = 8663218
677 + 8662541 = 8663218

Showing the first eight; more decompositions exist.
