Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172506, here are decompositions:

17 + 172489 = 172506
67 + 172439 = 172506
73 + 172433 = 172506
79 + 172427 = 172506
83 + 172423 = 172506
107 + 172399 = 172506
149 + 172357 = 172506
163 + 172343 = 172506

Showing the first eight; more decompositions exist.
