Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166658, here are decompositions:

31 + 166627 = 166658
61 + 166597 = 166658
97 + 166561 = 166658
229 + 166429 = 166658
241 + 166417 = 166658
307 + 166351 = 166658
421 + 166237 = 166658
439 + 166219 = 166658

Showing the first eight; more decompositions exist.
