Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172004, here are decompositions:

3 + 172001 = 172004
67 + 171937 = 172004
127 + 171877 = 172004
181 + 171823 = 172004
193 + 171811 = 172004
211 + 171793 = 172004
241 + 171763 = 172004
271 + 171733 = 172004

Showing the first eight; more decompositions exist.
