Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529280, here are decompositions:

7 + 529273 = 529280
43 + 529237 = 529280
67 + 529213 = 529280
97 + 529183 = 529280
127 + 529153 = 529280
151 + 529129 = 529280
163 + 529117 = 529280
229 + 529051 = 529280

Showing the first eight; more decompositions exist.
