Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7750, here are decompositions:

23 + 7727 = 7750
47 + 7703 = 7750
59 + 7691 = 7750
101 + 7649 = 7750
107 + 7643 = 7750
167 + 7583 = 7750
173 + 7577 = 7750
191 + 7559 = 7750

Showing the first eight; more decompositions exist.
