Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7738, here are decompositions:

11 + 7727 = 7738
47 + 7691 = 7738
89 + 7649 = 7738
131 + 7607 = 7738
149 + 7589 = 7738
179 + 7559 = 7738
191 + 7547 = 7738
197 + 7541 = 7738

Showing the first eight; more decompositions exist.
