Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621426, here are decompositions:

13 + 8621413 = 8621426
127 + 8621299 = 8621426
283 + 8621143 = 8621426
337 + 8621089 = 8621426
349 + 8621077 = 8621426
379 + 8621047 = 8621426
409 + 8621017 = 8621426
433 + 8620993 = 8621426

Showing the first eight; more decompositions exist.
