Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702278, here are decompositions:

47 + 8702231 = 8702278
71 + 8702207 = 8702278
89 + 8702189 = 8702278
227 + 8702051 = 8702278
269 + 8702009 = 8702278
281 + 8701997 = 8702278
317 + 8701961 = 8702278
401 + 8701877 = 8702278

Showing the first eight; more decompositions exist.
