Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12766, here are decompositions:

3 + 12763 = 12766
23 + 12743 = 12766
53 + 12713 = 12766
107 + 12659 = 12766
113 + 12653 = 12766
197 + 12569 = 12766
227 + 12539 = 12766
239 + 12527 = 12766

Showing the first eight; more decompositions exist.
