Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669390, here are decompositions:

61 + 8669329 = 8669390
73 + 8669317 = 8669390
97 + 8669293 = 8669390
139 + 8669251 = 8669390
151 + 8669239 = 8669390
157 + 8669233 = 8669390
211 + 8669179 = 8669390
277 + 8669113 = 8669390

Showing the first eight; more decompositions exist.
