Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512802, here are decompositions:

5 + 512797 = 512802
23 + 512779 = 512802
41 + 512761 = 512802
61 + 512741 = 512802
89 + 512713 = 512802
131 + 512671 = 512802
139 + 512663 = 512802
181 + 512621 = 512802

Showing the first eight; more decompositions exist.
