Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725444, here are decompositions:

23 + 8725421 = 8725444
47 + 8725397 = 8725444
53 + 8725391 = 8725444
83 + 8725361 = 8725444
137 + 8725307 = 8725444
191 + 8725253 = 8725444
227 + 8725217 = 8725444
311 + 8725133 = 8725444

Showing the first eight; more decompositions exist.
