Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509998, here are decompositions:

59 + 509939 = 509998
89 + 509909 = 509998
131 + 509867 = 509998
197 + 509801 = 509998
257 + 509741 = 509998
311 + 509687 = 509998
317 + 509681 = 509998
449 + 509549 = 509998

Showing the first eight; more decompositions exist.
