Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15744, here are decompositions:

5 + 15739 = 15744
7 + 15737 = 15744
11 + 15733 = 15744
13 + 15731 = 15744
17 + 15727 = 15744
61 + 15683 = 15744
73 + 15671 = 15744
83 + 15661 = 15744

Showing the first eight; more decompositions exist.
