Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172836, here are decompositions:

7 + 172829 = 172836
29 + 172807 = 172836
127 + 172709 = 172836
149 + 172687 = 172836
163 + 172673 = 172836
173 + 172663 = 172836
179 + 172657 = 172836
193 + 172643 = 172836

Showing the first eight; more decompositions exist.
