Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172556, here are decompositions:

3 + 172553 = 172556
37 + 172519 = 172556
67 + 172489 = 172556
157 + 172399 = 172556
199 + 172357 = 172556
277 + 172279 = 172556
313 + 172243 = 172556
337 + 172219 = 172556

Showing the first eight; more decompositions exist.
