Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7660, here are decompositions:

11 + 7649 = 7660
17 + 7643 = 7660
53 + 7607 = 7660
71 + 7589 = 7660
83 + 7577 = 7660
101 + 7559 = 7660
113 + 7547 = 7660
131 + 7529 = 7660

Showing the first eight; more decompositions exist.
