Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166402, here are decompositions:

3 + 166399 = 166402
53 + 166349 = 166402
83 + 166319 = 166402
101 + 166301 = 166402
113 + 166289 = 166402
233 + 166169 = 166402
251 + 166151 = 166402
359 + 166043 = 166402

Showing the first eight; more decompositions exist.
