Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89900, here are decompositions:

3 + 89897 = 89900
61 + 89839 = 89900
67 + 89833 = 89900
79 + 89821 = 89900
103 + 89797 = 89900
211 + 89689 = 89900
229 + 89671 = 89900
241 + 89659 = 89900

Showing the first eight; more decompositions exist.
