Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719778, here are decompositions:

7 + 8719771 = 8719778
31 + 8719747 = 8719778
79 + 8719699 = 8719778
97 + 8719681 = 8719778
211 + 8719567 = 8719778
229 + 8719549 = 8719778
337 + 8719441 = 8719778
601 + 8719177 = 8719778

Showing the first eight; more decompositions exist.
