Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7744, here are decompositions:

3 + 7741 = 7744
17 + 7727 = 7744
41 + 7703 = 7744
53 + 7691 = 7744
71 + 7673 = 7744
101 + 7643 = 7744
137 + 7607 = 7744
167 + 7577 = 7744

Showing the first eight; more decompositions exist.
