Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626730, here are decompositions:

31 + 8626699 = 8626730
61 + 8626669 = 8626730
109 + 8626621 = 8626730
127 + 8626603 = 8626730
181 + 8626549 = 8626730
223 + 8626507 = 8626730
271 + 8626459 = 8626730
313 + 8626417 = 8626730

Showing the first eight; more decompositions exist.
