Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621576, here are decompositions:

97 + 8621479 = 8621576
109 + 8621467 = 8621576
163 + 8621413 = 8621576
199 + 8621377 = 8621576
277 + 8621299 = 8621576
367 + 8621209 = 8621576
433 + 8621143 = 8621576
487 + 8621089 = 8621576

Showing the first eight; more decompositions exist.
