Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045872, here are decompositions:

13 + 1045859 = 1045872
31 + 1045841 = 1045872
43 + 1045829 = 1045872
53 + 1045819 = 1045872
71 + 1045801 = 1045872
73 + 1045799 = 1045872
109 + 1045763 = 1045872
181 + 1045691 = 1045872

Showing the first eight; more decompositions exist.
