Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641192, here are decompositions:

5 + 8641187 = 8641192
59 + 8641133 = 8641192
113 + 8641079 = 8641192
281 + 8640911 = 8641192
431 + 8640761 = 8641192
479 + 8640713 = 8641192
491 + 8640701 = 8641192
503 + 8640689 = 8641192

Showing the first eight; more decompositions exist.
