Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15738, here are decompositions:

5 + 15733 = 15738
7 + 15731 = 15738
11 + 15727 = 15738
59 + 15679 = 15738
67 + 15671 = 15738
71 + 15667 = 15738
89 + 15649 = 15738
97 + 15641 = 15738

Showing the first eight; more decompositions exist.
