Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621348, here are decompositions:

67 + 8621281 = 8621348
139 + 8621209 = 8621348
271 + 8621077 = 8621348
331 + 8621017 = 8621348
397 + 8620951 = 8621348
487 + 8620861 = 8621348
601 + 8620747 = 8621348
661 + 8620687 = 8621348

Showing the first eight; more decompositions exist.
