Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709558, here are decompositions:

5 + 8709553 = 8709558
31 + 8709527 = 8709558
89 + 8709469 = 8709558
97 + 8709461 = 8709558
127 + 8709431 = 8709558
181 + 8709377 = 8709558
197 + 8709361 = 8709558
241 + 8709317 = 8709558

Showing the first eight; more decompositions exist.
