Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626478, here are decompositions:

19 + 8626459 = 8626478
61 + 8626417 = 8626478
181 + 8626297 = 8626478
229 + 8626249 = 8626478
241 + 8626237 = 8626478
337 + 8626141 = 8626478
349 + 8626129 = 8626478
379 + 8626099 = 8626478

Showing the first eight; more decompositions exist.
