Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66266, here are decompositions:

97 + 66169 = 66266
157 + 66109 = 66266
163 + 66103 = 66266
199 + 66067 = 66266
229 + 66037 = 66266
283 + 65983 = 66266
337 + 65929 = 66266
367 + 65899 = 66266

Showing the first eight; more decompositions exist.
