Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166264, here are decompositions:

5 + 166259 = 166264
17 + 166247 = 166264
107 + 166157 = 166264
113 + 166151 = 166264
233 + 166031 = 166264
251 + 166013 = 166264
281 + 165983 = 166264
317 + 165947 = 166264

Showing the first eight; more decompositions exist.
