Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89990, here are decompositions:

7 + 89983 = 89990
13 + 89977 = 89990
31 + 89959 = 89990
67 + 89923 = 89990
73 + 89917 = 89990
151 + 89839 = 89990
157 + 89833 = 89990
181 + 89809 = 89990

Showing the first eight; more decompositions exist.
