Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29740, here are decompositions:

17 + 29723 = 29740
23 + 29717 = 29740
71 + 29669 = 29740
107 + 29633 = 29740
167 + 29573 = 29740
173 + 29567 = 29740
239 + 29501 = 29740
257 + 29483 = 29740

Showing the first eight; more decompositions exist.
