Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621234, here are decompositions:

151 + 8621083 = 8621234
157 + 8621077 = 8621234
241 + 8620993 = 8621234
283 + 8620951 = 8621234
337 + 8620897 = 8621234
373 + 8620861 = 8621234
487 + 8620747 = 8621234
547 + 8620687 = 8621234

Showing the first eight; more decompositions exist.
