Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172600, here are decompositions:

3 + 172597 = 172600
11 + 172589 = 172600
17 + 172583 = 172600
47 + 172553 = 172600
59 + 172541 = 172600
83 + 172517 = 172600
167 + 172433 = 172600
173 + 172427 = 172600

Showing the first eight; more decompositions exist.
