Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168836, here are decompositions:

67 + 168769 = 168836
139 + 168697 = 168836
163 + 168673 = 168836
193 + 168643 = 168836
277 + 168559 = 168836
313 + 168523 = 168836
337 + 168499 = 168836
373 + 168463 = 168836

Showing the first eight; more decompositions exist.
