Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621408, here are decompositions:

31 + 8621377 = 8621408
109 + 8621299 = 8621408
127 + 8621281 = 8621408
199 + 8621209 = 8621408
307 + 8621101 = 8621408
331 + 8621077 = 8621408
457 + 8620951 = 8621408
547 + 8620861 = 8621408

Showing the first eight; more decompositions exist.
