Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171480, here are decompositions:

7 + 171473 = 171480
11 + 171469 = 171480
13 + 171467 = 171480
31 + 171449 = 171480
41 + 171439 = 171480
53 + 171427 = 171480
79 + 171401 = 171480
97 + 171383 = 171480

Showing the first eight; more decompositions exist.
