Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 98870, here are decompositions:

3 + 98867 = 98870
61 + 98809 = 98870
97 + 98773 = 98870
139 + 98731 = 98870
157 + 98713 = 98870
181 + 98689 = 98870
229 + 98641 = 98870
307 + 98563 = 98870

Showing the first eight; more decompositions exist.
