Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172126, here are decompositions:

29 + 172097 = 172126
47 + 172079 = 172126
179 + 171947 = 172126
197 + 171929 = 172126
257 + 171869 = 172126
263 + 171863 = 172126
419 + 171707 = 172126
467 + 171659 = 172126

Showing the first eight; more decompositions exist.
