Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166434, here are decompositions:

5 + 166429 = 166434
17 + 166417 = 166434
31 + 166403 = 166434
41 + 166393 = 166434
71 + 166363 = 166434
83 + 166351 = 166434
131 + 166303 = 166434
137 + 166297 = 166434

Showing the first eight; more decompositions exist.
