Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051872, here are decompositions:

23 + 1051849 = 1051872
43 + 1051829 = 1051872
53 + 1051819 = 1051872
61 + 1051811 = 1051872
83 + 1051789 = 1051872
109 + 1051763 = 1051872
113 + 1051759 = 1051872
163 + 1051709 = 1051872

Showing the first eight; more decompositions exist.
