Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509824, here are decompositions:

23 + 509801 = 509824
41 + 509783 = 509824
83 + 509741 = 509824
101 + 509723 = 509824
131 + 509693 = 509824
137 + 509687 = 509824
191 + 509633 = 509824
233 + 509591 = 509824

Showing the first eight; more decompositions exist.
