Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611308, here are decompositions:

5 + 8611303 = 8611308
7 + 8611301 = 8611308
11 + 8611297 = 8611308
47 + 8611261 = 8611308
59 + 8611249 = 8611308
61 + 8611247 = 8611308
89 + 8611219 = 8611308
107 + 8611201 = 8611308

Showing the first eight; more decompositions exist.
