Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013870, here are decompositions:

19 + 1013851 = 1013870
31 + 1013839 = 1013870
37 + 1013833 = 1013870
43 + 1013827 = 1013870
79 + 1013791 = 1013870
97 + 1013773 = 1013870
103 + 1013767 = 1013870
157 + 1013713 = 1013870

Showing the first eight; more decompositions exist.
