Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166378, here are decompositions:

29 + 166349 = 166378
59 + 166319 = 166378
89 + 166289 = 166378
131 + 166247 = 166378
227 + 166151 = 166378
347 + 166031 = 166378
431 + 165947 = 166378
491 + 165887 = 166378

Showing the first eight; more decompositions exist.
