Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172468, here are decompositions:

29 + 172439 = 172468
41 + 172427 = 172468
47 + 172421 = 172468
137 + 172331 = 172468
251 + 172217 = 172468
269 + 172199 = 172468
311 + 172157 = 172468
389 + 172079 = 172468

Showing the first eight; more decompositions exist.
