Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172348, here are decompositions:

5 + 172343 = 172348
17 + 172331 = 172348
41 + 172307 = 172348
89 + 172259 = 172348
131 + 172217 = 172348
149 + 172199 = 172348
167 + 172181 = 172348
179 + 172169 = 172348

Showing the first eight; more decompositions exist.
