Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2606, here are decompositions:

13 + 2593 = 2606
67 + 2539 = 2606
103 + 2503 = 2606
139 + 2467 = 2606
223 + 2383 = 2606
229 + 2377 = 2606
313 + 2293 = 2606
337 + 2269 = 2606

Showing the first eight; more decompositions exist.
