Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89858, here are decompositions:

19 + 89839 = 89858
37 + 89821 = 89858
61 + 89797 = 89858
79 + 89779 = 89858
199 + 89659 = 89858
331 + 89527 = 89858
337 + 89521 = 89858
367 + 89491 = 89858

Showing the first eight; more decompositions exist.
