Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 527220, here are decompositions:

11 + 527209 = 527220
13 + 527207 = 527220
17 + 527203 = 527220
41 + 527179 = 527220
47 + 527173 = 527220
59 + 527161 = 527220
61 + 527159 = 527220
97 + 527123 = 527220

Showing the first eight; more decompositions exist.
