Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7668, here are decompositions:

19 + 7649 = 7668
29 + 7639 = 7668
47 + 7621 = 7668
61 + 7607 = 7668
79 + 7589 = 7668
107 + 7561 = 7668
109 + 7559 = 7668
127 + 7541 = 7668

Showing the first eight; more decompositions exist.
