Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515804, here are decompositions:

31 + 515773 = 515804
43 + 515761 = 515804
67 + 515737 = 515804
103 + 515701 = 515804
127 + 515677 = 515804
151 + 515653 = 515804
193 + 515611 = 515804
241 + 515563 = 515804

Showing the first eight; more decompositions exist.
