Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641136, here are decompositions:

3 + 8641133 = 8641136
43 + 8641093 = 8641136
73 + 8641063 = 8641136
277 + 8640859 = 8641136
313 + 8640823 = 8641136
337 + 8640799 = 8641136
349 + 8640787 = 8641136
397 + 8640739 = 8641136

Showing the first eight; more decompositions exist.
