Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172130, here are decompositions:

3 + 172127 = 172130
37 + 172093 = 172130
61 + 172069 = 172130
103 + 172027 = 172130
109 + 172021 = 172130
193 + 171937 = 172130
241 + 171889 = 172130
307 + 171823 = 172130

Showing the first eight; more decompositions exist.
