Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17750, here are decompositions:

3 + 17747 = 17750
13 + 17737 = 17750
37 + 17713 = 17750
43 + 17707 = 17750
67 + 17683 = 17750
127 + 17623 = 17750
151 + 17599 = 17750
181 + 17569 = 17750

Showing the first eight; more decompositions exist.
