Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17728, here are decompositions:

47 + 17681 = 17728
59 + 17669 = 17728
71 + 17657 = 17728
101 + 17627 = 17728
131 + 17597 = 17728
149 + 17579 = 17728
239 + 17489 = 17728
251 + 17477 = 17728

Showing the first eight; more decompositions exist.
