Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725360, here are decompositions:

3 + 8725357 = 8725360
41 + 8725319 = 8725360
53 + 8725307 = 8725360
107 + 8725253 = 8725360
227 + 8725133 = 8725360
257 + 8725103 = 8725360
269 + 8725091 = 8725360
431 + 8724929 = 8725360

Showing the first eight; more decompositions exist.
