Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670018, here are decompositions:

11 + 8670007 = 8670018
29 + 8669989 = 8670018
37 + 8669981 = 8670018
79 + 8669939 = 8670018
89 + 8669929 = 8670018
107 + 8669911 = 8670018
139 + 8669879 = 8670018
157 + 8669861 = 8670018

Showing the first eight; more decompositions exist.
