Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701864, here are decompositions:

11 + 8701853 = 8701864
53 + 8701811 = 8701864
107 + 8701757 = 8701864
233 + 8701631 = 8701864
293 + 8701571 = 8701864
461 + 8701403 = 8701864
593 + 8701271 = 8701864
653 + 8701211 = 8701864

Showing the first eight; more decompositions exist.
