Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719746, here are decompositions:

43 + 8719703 = 8719746
47 + 8719699 = 8719746
83 + 8719663 = 8719746
173 + 8719573 = 8719746
179 + 8719567 = 8719746
197 + 8719549 = 8719746
227 + 8719519 = 8719746
263 + 8719483 = 8719746

Showing the first eight; more decompositions exist.
