Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641330, here are decompositions:

3 + 8641327 = 8641330
11 + 8641319 = 8641330
29 + 8641301 = 8641330
41 + 8641289 = 8641330
83 + 8641247 = 8641330
197 + 8641133 = 8641330
233 + 8641097 = 8641330
251 + 8641079 = 8641330

Showing the first eight; more decompositions exist.
