Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649658, here are decompositions:

29 + 8649629 = 8649658
47 + 8649611 = 8649658
137 + 8649521 = 8649658
167 + 8649491 = 8649658
179 + 8649479 = 8649658
191 + 8649467 = 8649658
239 + 8649419 = 8649658
359 + 8649299 = 8649658

Showing the first eight; more decompositions exist.
