Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123266, here are decompositions:

7 + 123259 = 123266
37 + 123229 = 123266
97 + 123169 = 123266
139 + 123127 = 123266
313 + 122953 = 123266
337 + 122929 = 123266
379 + 122887 = 123266
397 + 122869 = 123266

Showing the first eight; more decompositions exist.
