Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628582, here are decompositions:

29 + 8628553 = 8628582
31 + 8628551 = 8628582
89 + 8628493 = 8628582
101 + 8628481 = 8628582
103 + 8628479 = 8628582
139 + 8628443 = 8628582
199 + 8628383 = 8628582
223 + 8628359 = 8628582

Showing the first eight; more decompositions exist.
