Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611266, here are decompositions:

5 + 8611261 = 8611266
17 + 8611249 = 8611266
19 + 8611247 = 8611266
47 + 8611219 = 8611266
127 + 8611139 = 8611266
149 + 8611117 = 8611266
229 + 8611037 = 8611266
233 + 8611033 = 8611266

Showing the first eight; more decompositions exist.
