Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3490, here are decompositions:

23 + 3467 = 3490
29 + 3461 = 3490
41 + 3449 = 3490
83 + 3407 = 3490
101 + 3389 = 3490
131 + 3359 = 3490
167 + 3323 = 3490
191 + 3299 = 3490

Showing the first eight; more decompositions exist.
