Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166584, here are decompositions:

13 + 166571 = 166584
17 + 166567 = 166584
23 + 166561 = 166584
43 + 166541 = 166584
97 + 166487 = 166584
113 + 166471 = 166584
127 + 166457 = 166584
167 + 166417 = 166584

Showing the first eight; more decompositions exist.
