Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7760, here are decompositions:

3 + 7757 = 7760
7 + 7753 = 7760
19 + 7741 = 7760
37 + 7723 = 7760
43 + 7717 = 7760
61 + 7699 = 7760
73 + 7687 = 7760
79 + 7681 = 7760

Showing the first eight; more decompositions exist.
