Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715550, here are decompositions:

101 + 8715449 = 8715550
149 + 8715401 = 8715550
167 + 8715383 = 8715550
227 + 8715323 = 8715550
281 + 8715269 = 8715550
317 + 8715233 = 8715550
359 + 8715191 = 8715550
443 + 8715107 = 8715550

Showing the first eight; more decompositions exist.
