Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509800, here are decompositions:

3 + 509797 = 509800
17 + 509783 = 509800
59 + 509741 = 509800
101 + 509699 = 509800
107 + 509693 = 509800
113 + 509687 = 509800
167 + 509633 = 509800
197 + 509603 = 509800

Showing the first eight; more decompositions exist.
