Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172002, here are decompositions:

73 + 171929 = 172002
79 + 171923 = 172002
113 + 171889 = 172002
139 + 171863 = 172002
151 + 171851 = 172002
179 + 171823 = 172002
191 + 171811 = 172002
199 + 171803 = 172002

Showing the first eight; more decompositions exist.
