Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172454, here are decompositions:

13 + 172441 = 172454
31 + 172423 = 172454
43 + 172411 = 172454
97 + 172357 = 172454
103 + 172351 = 172454
157 + 172297 = 172454
211 + 172243 = 172454
241 + 172213 = 172454

Showing the first eight; more decompositions exist.
