Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172492, here are decompositions:

3 + 172489 = 172492
53 + 172439 = 172492
59 + 172433 = 172492
71 + 172421 = 172492
149 + 172343 = 172492
179 + 172313 = 172492
233 + 172259 = 172492
269 + 172223 = 172492

Showing the first eight; more decompositions exist.
