Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707386, here are decompositions:

7 + 8707379 = 8707386
29 + 8707357 = 8707386
43 + 8707343 = 8707386
53 + 8707333 = 8707386
59 + 8707327 = 8707386
97 + 8707289 = 8707386
109 + 8707277 = 8707386
113 + 8707273 = 8707386

Showing the first eight; more decompositions exist.
