Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649012, here are decompositions:

11 + 8649001 = 8649012
59 + 8648953 = 8649012
83 + 8648929 = 8649012
89 + 8648923 = 8649012
131 + 8648881 = 8649012
149 + 8648863 = 8649012
173 + 8648839 = 8649012
179 + 8648833 = 8649012

Showing the first eight; more decompositions exist.
