Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86900, here are decompositions:

31 + 86869 = 86900
43 + 86857 = 86900
157 + 86743 = 86900
181 + 86719 = 86900
211 + 86689 = 86900
223 + 86677 = 86900
271 + 86629 = 86900
313 + 86587 = 86900

Showing the first eight; more decompositions exist.
