Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8604878, here are decompositions:

67 + 8604811 = 8604878
97 + 8604781 = 8604878
109 + 8604769 = 8604878
127 + 8604751 = 8604878
181 + 8604697 = 8604878
211 + 8604667 = 8604878
229 + 8604649 = 8604878
349 + 8604529 = 8604878

Showing the first eight; more decompositions exist.
