Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680290, here are decompositions:

13 + 8680277 = 8680290
23 + 8680267 = 8680290
41 + 8680249 = 8680290
61 + 8680229 = 8680290
71 + 8680219 = 8680290
89 + 8680201 = 8680290
103 + 8680187 = 8680290
137 + 8680153 = 8680290

Showing the first eight; more decompositions exist.
