Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719396, here are decompositions:

5 + 8719391 = 8719396
17 + 8719379 = 8719396
29 + 8719367 = 8719396
47 + 8719349 = 8719396
89 + 8719307 = 8719396
107 + 8719289 = 8719396
173 + 8719223 = 8719396
197 + 8719199 = 8719396

Showing the first eight; more decompositions exist.
