Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17758, here are decompositions:

11 + 17747 = 17758
29 + 17729 = 17758
89 + 17669 = 17758
101 + 17657 = 17758
131 + 17627 = 17758
149 + 17609 = 17758
179 + 17579 = 17758
239 + 17519 = 17758

Showing the first eight; more decompositions exist.
