Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621726, here are decompositions:

19 + 8621707 = 8621726
73 + 8621653 = 8621726
103 + 8621623 = 8621726
109 + 8621617 = 8621726
283 + 8621443 = 8621726
313 + 8621413 = 8621726
349 + 8621377 = 8621726
643 + 8621083 = 8621726

Showing the first eight; more decompositions exist.
