Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172826, here are decompositions:

19 + 172807 = 172826
67 + 172759 = 172826
109 + 172717 = 172826
139 + 172687 = 172826
163 + 172663 = 172826
193 + 172633 = 172826
223 + 172603 = 172826
229 + 172597 = 172826

Showing the first eight; more decompositions exist.
