Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172502, here are decompositions:

13 + 172489 = 172502
61 + 172441 = 172502
79 + 172423 = 172502
103 + 172399 = 172502
151 + 172351 = 172502
181 + 172321 = 172502
223 + 172279 = 172502
283 + 172219 = 172502

Showing the first eight; more decompositions exist.
