Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2750, here are decompositions:

19 + 2731 = 2750
31 + 2719 = 2750
37 + 2713 = 2750
43 + 2707 = 2750
61 + 2689 = 2750
67 + 2683 = 2750
73 + 2677 = 2750
79 + 2671 = 2750

Showing the first eight; more decompositions exist.
