Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126280, here are decompositions:

23 + 126257 = 126280
47 + 126233 = 126280
53 + 126227 = 126280
107 + 126173 = 126280
137 + 126143 = 126280
149 + 126131 = 126280
173 + 126107 = 126280
233 + 126047 = 126280

Showing the first eight; more decompositions exist.
