Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168806, here are decompositions:

3 + 168803 = 168806
37 + 168769 = 168806
109 + 168697 = 168806
163 + 168643 = 168806
283 + 168523 = 168806
307 + 168499 = 168806
349 + 168457 = 168806
373 + 168433 = 168806

Showing the first eight; more decompositions exist.
