Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725480, here are decompositions:

17 + 8725463 = 8725480
59 + 8725421 = 8725480
83 + 8725397 = 8725480
89 + 8725391 = 8725480
173 + 8725307 = 8725480
227 + 8725253 = 8725480
263 + 8725217 = 8725480
347 + 8725133 = 8725480

Showing the first eight; more decompositions exist.
