Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173646, here are decompositions:

17 + 173629 = 173646
29 + 173617 = 173646
47 + 173599 = 173646
73 + 173573 = 173646
97 + 173549 = 173646
103 + 173543 = 173646
107 + 173539 = 173646
149 + 173497 = 173646

Showing the first eight; more decompositions exist.
