Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668290, here are decompositions:

11 + 8668279 = 8668290
17 + 8668273 = 8668290
23 + 8668267 = 8668290
83 + 8668207 = 8668290
89 + 8668201 = 8668290
97 + 8668193 = 8668290
139 + 8668151 = 8668290
149 + 8668141 = 8668290

Showing the first eight; more decompositions exist.
