Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173572, here are decompositions:

11 + 173561 = 173572
23 + 173549 = 173572
29 + 173543 = 173572
41 + 173531 = 173572
71 + 173501 = 173572
89 + 173483 = 173572
263 + 173309 = 173572
281 + 173291 = 173572

Showing the first eight; more decompositions exist.
