Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2758, here are decompositions:

5 + 2753 = 2758
17 + 2741 = 2758
29 + 2729 = 2758
47 + 2711 = 2758
59 + 2699 = 2758
71 + 2687 = 2758
101 + 2657 = 2758
137 + 2621 = 2758

Showing the first eight; more decompositions exist.
