Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525586, here are decompositions:

3 + 525583 = 525586
53 + 525533 = 525586
227 + 525359 = 525586
233 + 525353 = 525586
419 + 525167 = 525586
443 + 525143 = 525586
449 + 525137 = 525586
557 + 525029 = 525586

Showing the first eight; more decompositions exist.
