Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701278, here are decompositions:

7 + 8701271 = 8701278
11 + 8701267 = 8701278
67 + 8701211 = 8701278
71 + 8701207 = 8701278
101 + 8701177 = 8701278
137 + 8701141 = 8701278
197 + 8701081 = 8701278
211 + 8701067 = 8701278

Showing the first eight; more decompositions exist.
