Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164242, here are decompositions:

3 + 164239 = 164242
11 + 164231 = 164242
41 + 164201 = 164242
59 + 164183 = 164242
149 + 164093 = 164242
191 + 164051 = 164242
251 + 163991 = 164242
263 + 163979 = 164242

Showing the first eight; more decompositions exist.
