Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89890, here are decompositions:

23 + 89867 = 89890
41 + 89849 = 89890
71 + 89819 = 89890
107 + 89783 = 89890
131 + 89759 = 89890
137 + 89753 = 89890
233 + 89657 = 89890
257 + 89633 = 89890

Showing the first eight; more decompositions exist.
