Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172012, here are decompositions:

3 + 172009 = 172012
11 + 172001 = 172012
83 + 171929 = 172012
89 + 171923 = 172012
131 + 171881 = 172012
149 + 171863 = 172012
251 + 171761 = 172012
293 + 171719 = 172012

Showing the first eight; more decompositions exist.
