Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641798, here are decompositions:

17 + 8641781 = 8641798
89 + 8641709 = 8641798
101 + 8641697 = 8641798
167 + 8641631 = 8641798
227 + 8641571 = 8641798
251 + 8641547 = 8641798
257 + 8641541 = 8641798
281 + 8641517 = 8641798

Showing the first eight; more decompositions exist.
