Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12762, here are decompositions:

5 + 12757 = 12762
19 + 12743 = 12762
23 + 12739 = 12762
41 + 12721 = 12762
59 + 12703 = 12762
73 + 12689 = 12762
103 + 12659 = 12762
109 + 12653 = 12762

Showing the first eight; more decompositions exist.
