Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515802, here are decompositions:

19 + 515783 = 515802
29 + 515773 = 515802
31 + 515771 = 515802
41 + 515761 = 515802
61 + 515741 = 515802
101 + 515701 = 515802
109 + 515693 = 515802
139 + 515663 = 515802

Showing the first eight; more decompositions exist.
