Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515264, here are decompositions:

31 + 515233 = 515264
37 + 515227 = 515264
73 + 515191 = 515264
223 + 515041 = 515264
331 + 514933 = 515264
397 + 514867 = 515264
433 + 514831 = 515264
523 + 514741 = 515264

Showing the first eight; more decompositions exist.
