Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7788, here are decompositions:

29 + 7759 = 7788
31 + 7757 = 7788
47 + 7741 = 7788
61 + 7727 = 7788
71 + 7717 = 7788
89 + 7699 = 7788
97 + 7691 = 7788
101 + 7687 = 7788

Showing the first eight; more decompositions exist.
