Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509804, here are decompositions:

3 + 509801 = 509804
7 + 509797 = 509804
37 + 509767 = 509804
67 + 509737 = 509804
73 + 509731 = 509804
151 + 509653 = 509804
157 + 509647 = 509804
181 + 509623 = 509804

Showing the first eight; more decompositions exist.
