Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980870, here are decompositions:

19 + 980851 = 980870
43 + 980827 = 980870
67 + 980803 = 980870
97 + 980773 = 980870
139 + 980731 = 980870
151 + 980719 = 980870
181 + 980689 = 980870
193 + 980677 = 980870

Showing the first eight; more decompositions exist.
