Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17740, here are decompositions:

3 + 17737 = 17740
11 + 17729 = 17740
59 + 17681 = 17740
71 + 17669 = 17740
83 + 17657 = 17740
113 + 17627 = 17740
131 + 17609 = 17740
167 + 17573 = 17740

Showing the first eight; more decompositions exist.
