Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15748, here are decompositions:

11 + 15737 = 15748
17 + 15731 = 15748
101 + 15647 = 15748
107 + 15641 = 15748
167 + 15581 = 15748
179 + 15569 = 15748
197 + 15551 = 15748
251 + 15497 = 15748

Showing the first eight; more decompositions exist.
