Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719404, here are decompositions:

13 + 8719391 = 8719404
37 + 8719367 = 8719404
97 + 8719307 = 8719404
101 + 8719303 = 8719404
103 + 8719301 = 8719404
131 + 8719273 = 8719404
151 + 8719253 = 8719404
181 + 8719223 = 8719404

Showing the first eight; more decompositions exist.
