Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172498, here are decompositions:

59 + 172439 = 172498
71 + 172427 = 172498
167 + 172331 = 172498
191 + 172307 = 172498
239 + 172259 = 172498
281 + 172217 = 172498
317 + 172181 = 172498
401 + 172097 = 172498

Showing the first eight; more decompositions exist.
