Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621306, here are decompositions:

7 + 8621299 = 8621306
97 + 8621209 = 8621306
163 + 8621143 = 8621306
223 + 8621083 = 8621306
229 + 8621077 = 8621306
313 + 8620993 = 8621306
409 + 8620897 = 8621306
433 + 8620873 = 8621306

Showing the first eight; more decompositions exist.
