Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621848, here are decompositions:

5 + 8621843 = 8621848
17 + 8621831 = 8621848
29 + 8621819 = 8621848
101 + 8621747 = 8621848
167 + 8621681 = 8621848
239 + 8621609 = 8621848
419 + 8621429 = 8621848
509 + 8621339 = 8621848

Showing the first eight; more decompositions exist.
