Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 982870, here are decompositions:

3 + 982867 = 982870
23 + 982847 = 982870
29 + 982841 = 982870
41 + 982829 = 982870
101 + 982769 = 982870
167 + 982703 = 982870
173 + 982697 = 982870
227 + 982643 = 982870

Showing the first eight; more decompositions exist.
