Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725450, here are decompositions:

29 + 8725421 = 8725450
53 + 8725397 = 8725450
59 + 8725391 = 8725450
89 + 8725361 = 8725450
131 + 8725319 = 8725450
197 + 8725253 = 8725450
233 + 8725217 = 8725450
311 + 8725139 = 8725450

Showing the first eight; more decompositions exist.
