Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621522, here are decompositions:

31 + 8621491 = 8621522
43 + 8621479 = 8621522
79 + 8621443 = 8621522
109 + 8621413 = 8621522
223 + 8621299 = 8621522
241 + 8621281 = 8621522
313 + 8621209 = 8621522
379 + 8621143 = 8621522

Showing the first eight; more decompositions exist.
