Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7648, here are decompositions:

5 + 7643 = 7648
41 + 7607 = 7648
59 + 7589 = 7648
71 + 7577 = 7648
89 + 7559 = 7648
101 + 7547 = 7648
107 + 7541 = 7648
131 + 7517 = 7648

Showing the first eight; more decompositions exist.
