Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649804, here are decompositions:

11 + 8649793 = 8649804
13 + 8649791 = 8649804
41 + 8649763 = 8649804
43 + 8649761 = 8649804
47 + 8649757 = 8649804
83 + 8649721 = 8649804
101 + 8649703 = 8649804
113 + 8649691 = 8649804

Showing the first eight; more decompositions exist.
