Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725402, here are decompositions:

3 + 8725399 = 8725402
5 + 8725397 = 8725402
11 + 8725391 = 8725402
41 + 8725361 = 8725402
83 + 8725319 = 8725402
149 + 8725253 = 8725402
263 + 8725139 = 8725402
269 + 8725133 = 8725402

Showing the first eight; more decompositions exist.
