Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528260, here are decompositions:

13 + 528247 = 528260
37 + 528223 = 528260
43 + 528217 = 528260
97 + 528163 = 528260
163 + 528097 = 528260
277 + 527983 = 528260
331 + 527929 = 528260
379 + 527881 = 528260

Showing the first eight; more decompositions exist.
