Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2742, here are decompositions:

11 + 2731 = 2742
13 + 2729 = 2742
23 + 2719 = 2742
29 + 2713 = 2742
31 + 2711 = 2742
43 + 2699 = 2742
53 + 2689 = 2742
59 + 2683 = 2742

Showing the first eight; more decompositions exist.
