Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166472, here are decompositions:

43 + 166429 = 166472
73 + 166399 = 166472
79 + 166393 = 166472
109 + 166363 = 166472
199 + 166273 = 166472
283 + 166189 = 166472
373 + 166099 = 166472
409 + 166063 = 166472

Showing the first eight; more decompositions exist.
