Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173660, here are decompositions:

13 + 173647 = 173660
31 + 173629 = 173660
43 + 173617 = 173660
61 + 173599 = 173660
163 + 173497 = 173660
229 + 173431 = 173660
313 + 173347 = 173660
367 + 173293 = 173660

Showing the first eight; more decompositions exist.
