Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173556, here are decompositions:

7 + 173549 = 173556
13 + 173543 = 173556
17 + 173539 = 173556
59 + 173497 = 173556
73 + 173483 = 173556
83 + 173473 = 173556
127 + 173429 = 173556
197 + 173359 = 173556

Showing the first eight; more decompositions exist.
