Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42166, here are decompositions:

83 + 42083 = 42166
149 + 42017 = 42166
167 + 41999 = 42166
197 + 41969 = 42166
239 + 41927 = 42166
263 + 41903 = 42166
269 + 41897 = 42166
317 + 41849 = 42166

Showing the first eight; more decompositions exist.
