Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173020, here are decompositions:

47 + 172973 = 173020
137 + 172883 = 173020
149 + 172871 = 173020
167 + 172853 = 173020
191 + 172829 = 173020
233 + 172787 = 173020
269 + 172751 = 173020
311 + 172709 = 173020

Showing the first eight; more decompositions exist.
