Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709538, here are decompositions:

11 + 8709527 = 8709538
29 + 8709509 = 8709538
107 + 8709431 = 8709538
239 + 8709299 = 8709538
281 + 8709257 = 8709538
317 + 8709221 = 8709538
347 + 8709191 = 8709538
389 + 8709149 = 8709538

Showing the first eight; more decompositions exist.
