Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009872, here are decompositions:

13 + 1009859 = 1009872
29 + 1009843 = 1009872
53 + 1009819 = 1009872
131 + 1009741 = 1009872
223 + 1009649 = 1009872
229 + 1009643 = 1009872
251 + 1009621 = 1009872
263 + 1009609 = 1009872

Showing the first eight; more decompositions exist.
