Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171554, here are decompositions:

13 + 171541 = 171554
37 + 171517 = 171554
73 + 171481 = 171554
127 + 171427 = 171554
151 + 171403 = 171554
283 + 171271 = 171554
463 + 171091 = 171554
547 + 171007 = 171554

Showing the first eight; more decompositions exist.
