Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172452, here are decompositions:

11 + 172441 = 172452
13 + 172439 = 172452
19 + 172433 = 172452
29 + 172423 = 172452
31 + 172421 = 172452
41 + 172411 = 172452
53 + 172399 = 172452
79 + 172373 = 172452

Showing the first eight; more decompositions exist.
