Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701398, here are decompositions:

7 + 8701391 = 8701398
31 + 8701367 = 8701398
89 + 8701309 = 8701398
109 + 8701289 = 8701398
127 + 8701271 = 8701398
131 + 8701267 = 8701398
191 + 8701207 = 8701398
257 + 8701141 = 8701398

Showing the first eight; more decompositions exist.
