Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168582, here are decompositions:

23 + 168559 = 168582
41 + 168541 = 168582
59 + 168523 = 168582
83 + 168499 = 168582
101 + 168481 = 168582
131 + 168451 = 168582
149 + 168433 = 168582
173 + 168409 = 168582

Showing the first eight; more decompositions exist.
