Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2762, here are decompositions:

13 + 2749 = 2762
31 + 2731 = 2762
43 + 2719 = 2762
73 + 2689 = 2762
79 + 2683 = 2762
103 + 2659 = 2762
211 + 2551 = 2762
223 + 2539 = 2762

Showing the first eight; more decompositions exist.
