Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7690, here are decompositions:

3 + 7687 = 7690
17 + 7673 = 7690
41 + 7649 = 7690
47 + 7643 = 7690
83 + 7607 = 7690
101 + 7589 = 7690
107 + 7583 = 7690
113 + 7577 = 7690

Showing the first eight; more decompositions exist.
