Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515006, here are decompositions:

67 + 514939 = 515006
73 + 514933 = 515006
103 + 514903 = 515006
139 + 514867 = 515006
223 + 514783 = 515006
337 + 514669 = 515006
367 + 514639 = 515006
463 + 514543 = 515006

Showing the first eight; more decompositions exist.
