Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166394, here are decompositions:

31 + 166363 = 166394
37 + 166357 = 166394
43 + 166351 = 166394
97 + 166297 = 166394
157 + 166237 = 166394
211 + 166183 = 166394
313 + 166081 = 166394
331 + 166063 = 166394

Showing the first eight; more decompositions exist.
