Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649900, here are decompositions:

13 + 8649887 = 8649900
19 + 8649881 = 8649900
29 + 8649871 = 8649900
31 + 8649869 = 8649900
43 + 8649857 = 8649900
47 + 8649853 = 8649900
53 + 8649847 = 8649900
97 + 8649803 = 8649900

Showing the first eight; more decompositions exist.
