Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003872, here are decompositions:

31 + 1003841 = 1003872
53 + 1003819 = 1003872
101 + 1003771 = 1003872
109 + 1003763 = 1003872
131 + 1003741 = 1003872
139 + 1003733 = 1003872
179 + 1003693 = 1003872
193 + 1003679 = 1003872

Showing the first eight; more decompositions exist.
