Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521588, here are decompositions:

7 + 521581 = 521588
31 + 521557 = 521588
37 + 521551 = 521588
61 + 521527 = 521588
97 + 521491 = 521588
211 + 521377 = 521588
229 + 521359 = 521588
271 + 521317 = 521588

Showing the first eight; more decompositions exist.
