Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99870, here are decompositions:

11 + 99859 = 99870
31 + 99839 = 99870
37 + 99833 = 99870
41 + 99829 = 99870
47 + 99823 = 99870
53 + 99817 = 99870
61 + 99809 = 99870
83 + 99787 = 99870

Showing the first eight; more decompositions exist.
