Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1058840, here are decompositions:

19 + 1058821 = 1058840
31 + 1058809 = 1058840
37 + 1058803 = 1058840
61 + 1058779 = 1058840
67 + 1058773 = 1058840
73 + 1058767 = 1058840
109 + 1058731 = 1058840
157 + 1058683 = 1058840

Showing the first eight; more decompositions exist.
