Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3290, here are decompositions:

19 + 3271 = 3290
31 + 3259 = 3290
37 + 3253 = 3290
61 + 3229 = 3290
73 + 3217 = 3290
103 + 3187 = 3290
109 + 3181 = 3290
127 + 3163 = 3290

Showing the first eight; more decompositions exist.
