Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621482, here are decompositions:

3 + 8621479 = 8621482
5 + 8621477 = 8621482
29 + 8621453 = 8621482
53 + 8621429 = 8621482
71 + 8621411 = 8621482
173 + 8621309 = 8621482
239 + 8621243 = 8621482
269 + 8621213 = 8621482

Showing the first eight; more decompositions exist.
