Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1052870, here are decompositions:

19 + 1052851 = 1052870
67 + 1052803 = 1052870
73 + 1052797 = 1052870
103 + 1052767 = 1052870
127 + 1052743 = 1052870
139 + 1052731 = 1052870
151 + 1052719 = 1052870
163 + 1052707 = 1052870

Showing the first eight; more decompositions exist.
