Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7678, here are decompositions:

5 + 7673 = 7678
29 + 7649 = 7678
71 + 7607 = 7678
89 + 7589 = 7678
101 + 7577 = 7678
131 + 7547 = 7678
137 + 7541 = 7678
149 + 7529 = 7678

Showing the first eight; more decompositions exist.
