Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709426, here are decompositions:

43 + 8709383 = 8709426
53 + 8709373 = 8709426
109 + 8709317 = 8709426
113 + 8709313 = 8709426
127 + 8709299 = 8709426
137 + 8709289 = 8709426
197 + 8709229 = 8709426
239 + 8709187 = 8709426

Showing the first eight; more decompositions exist.
