Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525520, here are decompositions:

3 + 525517 = 525520
29 + 525491 = 525520
53 + 525467 = 525520
59 + 525461 = 525520
89 + 525431 = 525520
167 + 525353 = 525520
263 + 525257 = 525520
311 + 525209 = 525520

Showing the first eight; more decompositions exist.
