Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172474, here are decompositions:

41 + 172433 = 172474
47 + 172427 = 172474
53 + 172421 = 172474
101 + 172373 = 172474
131 + 172343 = 172474
167 + 172307 = 172474
191 + 172283 = 172474
251 + 172223 = 172474

Showing the first eight; more decompositions exist.
