Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172494, here are decompositions:

5 + 172489 = 172494
53 + 172441 = 172494
61 + 172433 = 172494
67 + 172427 = 172494
71 + 172423 = 172494
73 + 172421 = 172494
83 + 172411 = 172494
137 + 172357 = 172494

Showing the first eight; more decompositions exist.
