Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709386, here are decompositions:

3 + 8709383 = 8709386
13 + 8709373 = 8709386
73 + 8709313 = 8709386
97 + 8709289 = 8709386
157 + 8709229 = 8709386
199 + 8709187 = 8709386
307 + 8709079 = 8709386
379 + 8709007 = 8709386

Showing the first eight; more decompositions exist.
