Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168506, here are decompositions:

7 + 168499 = 168506
43 + 168463 = 168506
73 + 168433 = 168506
97 + 168409 = 168506
229 + 168277 = 168506
313 + 168193 = 168506
379 + 168127 = 168506
397 + 168109 = 168506

Showing the first eight; more decompositions exist.
