Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641194, here are decompositions:

7 + 8641187 = 8641194
47 + 8641147 = 8641194
61 + 8641133 = 8641194
97 + 8641097 = 8641194
101 + 8641093 = 8641194
131 + 8641063 = 8641194
227 + 8640967 = 8641194
283 + 8640911 = 8641194

Showing the first eight; more decompositions exist.
