Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172450, here are decompositions:

11 + 172439 = 172450
17 + 172433 = 172450
23 + 172427 = 172450
29 + 172421 = 172450
107 + 172343 = 172450
137 + 172313 = 172450
167 + 172283 = 172450
191 + 172259 = 172450

Showing the first eight; more decompositions exist.
