Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621696, here are decompositions:

3 + 8621693 = 8621696
19 + 8621677 = 8621696
43 + 8621653 = 8621696
73 + 8621623 = 8621696
79 + 8621617 = 8621696
229 + 8621467 = 8621696
283 + 8621413 = 8621696
397 + 8621299 = 8621696

Showing the first eight; more decompositions exist.
