Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649406, here are decompositions:

23 + 8649383 = 8649406
53 + 8649353 = 8649406
83 + 8649323 = 8649406
89 + 8649317 = 8649406
107 + 8649299 = 8649406
113 + 8649293 = 8649406
167 + 8649239 = 8649406
179 + 8649227 = 8649406

Showing the first eight; more decompositions exist.
