Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166504, here are decompositions:

17 + 166487 = 166504
47 + 166457 = 166504
101 + 166403 = 166504
257 + 166247 = 166504
347 + 166157 = 166504
353 + 166151 = 166504
461 + 166043 = 166504
491 + 166013 = 166504

Showing the first eight; more decompositions exist.
