Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649894, here are decompositions:

7 + 8649887 = 8649894
13 + 8649881 = 8649894
23 + 8649871 = 8649894
37 + 8649857 = 8649894
41 + 8649853 = 8649894
47 + 8649847 = 8649894
101 + 8649793 = 8649894
103 + 8649791 = 8649894

Showing the first eight; more decompositions exist.
