Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515258, here are decompositions:

31 + 515227 = 515258
67 + 515191 = 515258
109 + 515149 = 515258
439 + 514819 = 515258
547 + 514711 = 515258
577 + 514681 = 515258
607 + 514651 = 515258
619 + 514639 = 515258

Showing the first eight; more decompositions exist.
