Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649400, here are decompositions:

17 + 8649383 = 8649400
29 + 8649371 = 8649400
47 + 8649353 = 8649400
83 + 8649317 = 8649400
101 + 8649299 = 8649400
107 + 8649293 = 8649400
173 + 8649227 = 8649400
479 + 8648921 = 8649400

Showing the first eight; more decompositions exist.
