Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172486, here are decompositions:

47 + 172439 = 172486
53 + 172433 = 172486
59 + 172427 = 172486
113 + 172373 = 172486
173 + 172313 = 172486
179 + 172307 = 172486
227 + 172259 = 172486
263 + 172223 = 172486

Showing the first eight; more decompositions exist.
