Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509872, here are decompositions:

5 + 509867 = 509872
29 + 509843 = 509872
71 + 509801 = 509872
89 + 509783 = 509872
131 + 509741 = 509872
149 + 509723 = 509872
173 + 509699 = 509872
179 + 509693 = 509872

Showing the first eight; more decompositions exist.
