Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 174540, here are decompositions:

7 + 174533 = 174540
13 + 174527 = 174540
53 + 174487 = 174540
59 + 174481 = 174540
71 + 174469 = 174540
73 + 174467 = 174540
83 + 174457 = 174540
97 + 174443 = 174540

Showing the first eight; more decompositions exist.
