Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709340, here are decompositions:

23 + 8709317 = 8709340
41 + 8709299 = 8709340
83 + 8709257 = 8709340
149 + 8709191 = 8709340
191 + 8709149 = 8709340
281 + 8709059 = 8709340
491 + 8708849 = 8709340
509 + 8708831 = 8709340

Showing the first eight; more decompositions exist.
