Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701290, here are decompositions:

11 + 8701279 = 8701290
19 + 8701271 = 8701290
23 + 8701267 = 8701290
47 + 8701243 = 8701290
79 + 8701211 = 8701290
83 + 8701207 = 8701290
97 + 8701193 = 8701290
113 + 8701177 = 8701290

Showing the first eight; more decompositions exist.
