Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641342, here are decompositions:

11 + 8641331 = 8641342
23 + 8641319 = 8641342
41 + 8641301 = 8641342
53 + 8641289 = 8641342
131 + 8641211 = 8641342
263 + 8641079 = 8641342
431 + 8640911 = 8641342
641 + 8640701 = 8641342

Showing the first eight; more decompositions exist.
