Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646668, here are decompositions:

61 + 8646607 = 8646668
97 + 8646571 = 8646668
109 + 8646559 = 8646668
139 + 8646529 = 8646668
157 + 8646511 = 8646668
181 + 8646487 = 8646668
211 + 8646457 = 8646668
307 + 8646361 = 8646668

Showing the first eight; more decompositions exist.
