Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1007872, here are decompositions:

11 + 1007861 = 1007872
53 + 1007819 = 1007872
59 + 1007813 = 1007872
71 + 1007801 = 1007872
83 + 1007789 = 1007872
101 + 1007771 = 1007872
113 + 1007759 = 1007872
149 + 1007723 = 1007872

Showing the first eight; more decompositions exist.
