Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487266, here are decompositions:

5 + 487261 = 487266
19 + 487247 = 487266
47 + 487219 = 487266
53 + 487213 = 487266
79 + 487187 = 487266
83 + 487183 = 487266
89 + 487177 = 487266
167 + 487099 = 487266

Showing the first eight; more decompositions exist.
