Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515828, here are decompositions:

67 + 515761 = 515828
127 + 515701 = 515828
151 + 515677 = 515828
241 + 515587 = 515828
457 + 515371 = 515828
601 + 515227 = 515828
739 + 515089 = 515828
787 + 515041 = 515828

Showing the first eight; more decompositions exist.
