Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7756, here are decompositions:

3 + 7753 = 7756
29 + 7727 = 7756
53 + 7703 = 7756
83 + 7673 = 7756
107 + 7649 = 7756
113 + 7643 = 7756
149 + 7607 = 7756
167 + 7589 = 7756

Showing the first eight; more decompositions exist.
