Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649586, here are decompositions:

5 + 8649581 = 8649586
53 + 8649533 = 8649586
107 + 8649479 = 8649586
167 + 8649419 = 8649586
233 + 8649353 = 8649586
263 + 8649323 = 8649586
269 + 8649317 = 8649586
293 + 8649293 = 8649586

Showing the first eight; more decompositions exist.
