Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719408, here are decompositions:

17 + 8719391 = 8719408
29 + 8719379 = 8719408
41 + 8719367 = 8719408
59 + 8719349 = 8719408
101 + 8719307 = 8719408
107 + 8719301 = 8719408
197 + 8719211 = 8719408
281 + 8719127 = 8719408

Showing the first eight; more decompositions exist.
