Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172554, here are decompositions:

13 + 172541 = 172554
37 + 172517 = 172554
47 + 172507 = 172554
113 + 172441 = 172554
127 + 172427 = 172554
131 + 172423 = 172554
181 + 172373 = 172554
197 + 172357 = 172554

Showing the first eight; more decompositions exist.
