Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172250, here are decompositions:

7 + 172243 = 172250
31 + 172219 = 172250
37 + 172213 = 172250
79 + 172171 = 172250
97 + 172153 = 172250
103 + 172147 = 172250
157 + 172093 = 172250
181 + 172069 = 172250

Showing the first eight; more decompositions exist.
