Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702458, here are decompositions:

47 + 8702411 = 8702458
71 + 8702387 = 8702458
131 + 8702327 = 8702458
179 + 8702279 = 8702458
227 + 8702231 = 8702458
251 + 8702207 = 8702458
269 + 8702189 = 8702458
449 + 8702009 = 8702458

Showing the first eight; more decompositions exist.
