Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621458, here are decompositions:

5 + 8621453 = 8621458
29 + 8621429 = 8621458
47 + 8621411 = 8621458
149 + 8621309 = 8621458
257 + 8621201 = 8621458
269 + 8621189 = 8621458
311 + 8621147 = 8621458
449 + 8621009 = 8621458

Showing the first eight; more decompositions exist.
