Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18290, here are decompositions:

3 + 18287 = 18290
37 + 18253 = 18290
61 + 18229 = 18290
67 + 18223 = 18290
73 + 18217 = 18290
79 + 18211 = 18290
109 + 18181 = 18290
157 + 18133 = 18290

Showing the first eight; more decompositions exist.
