Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17540, here are decompositions:

31 + 17509 = 17540
43 + 17497 = 17540
73 + 17467 = 17540
97 + 17443 = 17540
109 + 17431 = 17540
139 + 17401 = 17540
151 + 17389 = 17540
157 + 17383 = 17540

Showing the first eight; more decompositions exist.
