Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7688, here are decompositions:

7 + 7681 = 7688
19 + 7669 = 7688
67 + 7621 = 7688
97 + 7591 = 7688
127 + 7561 = 7688
139 + 7549 = 7688
151 + 7537 = 7688
181 + 7507 = 7688

Showing the first eight; more decompositions exist.
