Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168722, here are decompositions:

3 + 168719 = 168722
79 + 168643 = 168722
163 + 168559 = 168722
181 + 168541 = 168722
199 + 168523 = 168722
223 + 168499 = 168722
241 + 168481 = 168722
271 + 168451 = 168722

Showing the first eight; more decompositions exist.
