Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649520, here are decompositions:

3 + 8649517 = 8649520
29 + 8649491 = 8649520
41 + 8649479 = 8649520
53 + 8649467 = 8649520
101 + 8649419 = 8649520
137 + 8649383 = 8649520
149 + 8649371 = 8649520
167 + 8649353 = 8649520

Showing the first eight; more decompositions exist.
