Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641090, here are decompositions:

11 + 8641079 = 8641090
83 + 8641007 = 8641090
113 + 8640977 = 8641090
179 + 8640911 = 8641090
383 + 8640707 = 8641090
389 + 8640701 = 8641090
401 + 8640689 = 8641090
503 + 8640587 = 8641090

Showing the first eight; more decompositions exist.
