Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649880, here are decompositions:

11 + 8649869 = 8649880
23 + 8649857 = 8649880
89 + 8649791 = 8649880
191 + 8649689 = 8649880
251 + 8649629 = 8649880
257 + 8649623 = 8649880
269 + 8649611 = 8649880
347 + 8649533 = 8649880

Showing the first eight; more decompositions exist.
