Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709658, here are decompositions:

5 + 8709653 = 8709658
11 + 8709647 = 8709658
47 + 8709611 = 8709658
71 + 8709587 = 8709658
131 + 8709527 = 8709658
149 + 8709509 = 8709658
197 + 8709461 = 8709658
227 + 8709431 = 8709658

Showing the first eight; more decompositions exist.
