Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173742, here are decompositions:

13 + 173729 = 173742
29 + 173713 = 173742
43 + 173699 = 173742
59 + 173683 = 173742
71 + 173671 = 173742
73 + 173669 = 173742
83 + 173659 = 173742
113 + 173629 = 173742

Showing the first eight; more decompositions exist.
