Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719730, here are decompositions:

31 + 8719699 = 8719730
67 + 8719663 = 8719730
127 + 8719603 = 8719730
139 + 8719591 = 8719730
157 + 8719573 = 8719730
163 + 8719567 = 8719730
181 + 8719549 = 8719730
211 + 8719519 = 8719730

Showing the first eight; more decompositions exist.
