Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2746, here are decompositions:

5 + 2741 = 2746
17 + 2729 = 2746
47 + 2699 = 2746
53 + 2693 = 2746
59 + 2687 = 2746
83 + 2663 = 2746
89 + 2657 = 2746
113 + 2633 = 2746

Showing the first eight; more decompositions exist.
