Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707398, here are decompositions:

5 + 8707393 = 8707398
19 + 8707379 = 8707398
41 + 8707357 = 8707398
47 + 8707351 = 8707398
71 + 8707327 = 8707398
109 + 8707289 = 8707398
157 + 8707241 = 8707398
179 + 8707219 = 8707398

Showing the first eight; more decompositions exist.
