Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641078, here are decompositions:

71 + 8641007 = 8641078
101 + 8640977 = 8641078
167 + 8640911 = 8641078
191 + 8640887 = 8641078
311 + 8640767 = 8641078
317 + 8640761 = 8641078
359 + 8640719 = 8641078
389 + 8640689 = 8641078

Showing the first eight; more decompositions exist.
