Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172426, here are decompositions:

3 + 172423 = 172426
5 + 172421 = 172426
53 + 172373 = 172426
83 + 172343 = 172426
113 + 172313 = 172426
167 + 172259 = 172426
227 + 172199 = 172426
257 + 172169 = 172426

Showing the first eight; more decompositions exist.
