Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611320, here are decompositions:

13 + 8611307 = 8611320
17 + 8611303 = 8611320
19 + 8611301 = 8611320
23 + 8611297 = 8611320
37 + 8611283 = 8611320
59 + 8611261 = 8611320
71 + 8611249 = 8611320
73 + 8611247 = 8611320

Showing the first eight; more decompositions exist.
