Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725404, here are decompositions:

5 + 8725399 = 8725404
7 + 8725397 = 8725404
13 + 8725391 = 8725404
41 + 8725363 = 8725404
43 + 8725361 = 8725404
47 + 8725357 = 8725404
97 + 8725307 = 8725404
151 + 8725253 = 8725404

Showing the first eight; more decompositions exist.
