Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709406, here are decompositions:

23 + 8709383 = 8709406
29 + 8709377 = 8709406
89 + 8709317 = 8709406
107 + 8709299 = 8709406
149 + 8709257 = 8709406
257 + 8709149 = 8709406
347 + 8709059 = 8709406
443 + 8708963 = 8709406

Showing the first eight; more decompositions exist.
