Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166534, here are decompositions:

47 + 166487 = 166534
131 + 166403 = 166534
233 + 166301 = 166534
383 + 166151 = 166534
491 + 166043 = 166534
503 + 166031 = 166534
521 + 166013 = 166534
587 + 165947 = 166534

Showing the first eight; more decompositions exist.
