Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722404, here are decompositions:

11 + 8722393 = 8722404
13 + 8722391 = 8722404
37 + 8722367 = 8722404
43 + 8722361 = 8722404
71 + 8722333 = 8722404
73 + 8722331 = 8722404
101 + 8722303 = 8722404
107 + 8722297 = 8722404

Showing the first eight; more decompositions exist.
