Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509844, here are decompositions:

7 + 509837 = 509844
11 + 509833 = 509844
43 + 509801 = 509844
47 + 509797 = 509844
61 + 509783 = 509844
103 + 509741 = 509844
107 + 509737 = 509844
113 + 509731 = 509844

Showing the first eight; more decompositions exist.
