Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2770, here are decompositions:

3 + 2767 = 2770
17 + 2753 = 2770
29 + 2741 = 2770
41 + 2729 = 2770
59 + 2711 = 2770
71 + 2699 = 2770
83 + 2687 = 2770
107 + 2663 = 2770

Showing the first eight; more decompositions exist.
