Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7700, here are decompositions:

13 + 7687 = 7700
19 + 7681 = 7700
31 + 7669 = 7700
61 + 7639 = 7700
79 + 7621 = 7700
97 + 7603 = 7700
109 + 7591 = 7700
127 + 7573 = 7700

Showing the first eight; more decompositions exist.
