Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171472, here are decompositions:

3 + 171469 = 171472
5 + 171467 = 171472
23 + 171449 = 171472
71 + 171401 = 171472
89 + 171383 = 171472
131 + 171341 = 171472
173 + 171299 = 171472
179 + 171293 = 171472

Showing the first eight; more decompositions exist.
