Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509944, here are decompositions:

5 + 509939 = 509944
23 + 509921 = 509944
101 + 509843 = 509944
107 + 509837 = 509944
251 + 509693 = 509944
257 + 509687 = 509944
263 + 509681 = 509944
311 + 509633 = 509944

Showing the first eight; more decompositions exist.
