Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621324, here are decompositions:

43 + 8621281 = 8621324
181 + 8621143 = 8621324
223 + 8621101 = 8621324
241 + 8621083 = 8621324
277 + 8621047 = 8621324
307 + 8621017 = 8621324
331 + 8620993 = 8621324
373 + 8620951 = 8621324

Showing the first eight; more decompositions exist.
