Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641324, here are decompositions:

5 + 8641319 = 8641324
23 + 8641301 = 8641324
113 + 8641211 = 8641324
137 + 8641187 = 8641324
191 + 8641133 = 8641324
227 + 8641097 = 8641324
317 + 8641007 = 8641324
347 + 8640977 = 8641324

Showing the first eight; more decompositions exist.
