Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23290, here are decompositions:

11 + 23279 = 23290
89 + 23201 = 23290
101 + 23189 = 23290
131 + 23159 = 23290
173 + 23117 = 23290
191 + 23099 = 23290
227 + 23063 = 23290
233 + 23057 = 23290

Showing the first eight; more decompositions exist.
