Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641260, here are decompositions:

11 + 8641249 = 8641260
13 + 8641247 = 8641260
29 + 8641231 = 8641260
73 + 8641187 = 8641260
113 + 8641147 = 8641260
127 + 8641133 = 8641260
163 + 8641097 = 8641260
167 + 8641093 = 8641260

Showing the first eight; more decompositions exist.
