Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701320, here are decompositions:

11 + 8701309 = 8701320
31 + 8701289 = 8701320
41 + 8701279 = 8701320
53 + 8701267 = 8701320
109 + 8701211 = 8701320
113 + 8701207 = 8701320
127 + 8701193 = 8701320
157 + 8701163 = 8701320

Showing the first eight; more decompositions exist.
