Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172562, here are decompositions:

43 + 172519 = 172562
73 + 172489 = 172562
139 + 172423 = 172562
151 + 172411 = 172562
163 + 172399 = 172562
211 + 172351 = 172562
241 + 172321 = 172562
283 + 172279 = 172562

Showing the first eight; more decompositions exist.
