Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166452, here are decompositions:

23 + 166429 = 166452
43 + 166409 = 166452
53 + 166399 = 166452
59 + 166393 = 166452
89 + 166363 = 166452
101 + 166351 = 166452
103 + 166349 = 166452
149 + 166303 = 166452

Showing the first eight; more decompositions exist.
