Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649120, here are decompositions:

17 + 8649103 = 8649120
41 + 8649079 = 8649120
59 + 8649061 = 8649120
71 + 8649049 = 8649120
97 + 8649023 = 8649120
167 + 8648953 = 8649120
191 + 8648929 = 8649120
197 + 8648923 = 8649120

Showing the first eight; more decompositions exist.
