Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621846, here are decompositions:

3 + 8621843 = 8621846
19 + 8621827 = 8621846
67 + 8621779 = 8621846
73 + 8621773 = 8621846
97 + 8621749 = 8621846
139 + 8621707 = 8621846
193 + 8621653 = 8621846
223 + 8621623 = 8621846

Showing the first eight; more decompositions exist.
