Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172446, here are decompositions:

5 + 172441 = 172446
7 + 172439 = 172446
13 + 172433 = 172446
19 + 172427 = 172446
23 + 172423 = 172446
47 + 172399 = 172446
73 + 172373 = 172446
89 + 172357 = 172446

Showing the first eight; more decompositions exist.
