Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15754, here are decompositions:

5 + 15749 = 15754
17 + 15737 = 15754
23 + 15731 = 15754
71 + 15683 = 15754
83 + 15671 = 15754
107 + 15647 = 15754
113 + 15641 = 15754
173 + 15581 = 15754

Showing the first eight; more decompositions exist.
