Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626946, here are decompositions:

19 + 8626927 = 8626946
43 + 8626903 = 8626946
127 + 8626819 = 8626946
199 + 8626747 = 8626946
277 + 8626669 = 8626946
397 + 8626549 = 8626946
439 + 8626507 = 8626946
487 + 8626459 = 8626946

Showing the first eight; more decompositions exist.
