Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15736, here are decompositions:

3 + 15733 = 15736
5 + 15731 = 15736
53 + 15683 = 15736
89 + 15647 = 15736
107 + 15629 = 15736
167 + 15569 = 15736
239 + 15497 = 15736
263 + 15473 = 15736

Showing the first eight; more decompositions exist.
