Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172560, here are decompositions:

7 + 172553 = 172560
19 + 172541 = 172560
41 + 172519 = 172560
43 + 172517 = 172560
53 + 172507 = 172560
71 + 172489 = 172560
127 + 172433 = 172560
137 + 172423 = 172560

Showing the first eight; more decompositions exist.
