Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2760, here are decompositions:

7 + 2753 = 2760
11 + 2749 = 2760
19 + 2741 = 2760
29 + 2731 = 2760
31 + 2729 = 2760
41 + 2719 = 2760
47 + 2713 = 2760
53 + 2707 = 2760

Showing the first eight; more decompositions exist.
