Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1030872, here are decompositions:

5 + 1030867 = 1030872
41 + 1030831 = 1030872
61 + 1030811 = 1030872
71 + 1030801 = 1030872
79 + 1030793 = 1030872
109 + 1030763 = 1030872
113 + 1030759 = 1030872
131 + 1030741 = 1030872

Showing the first eight; more decompositions exist.
