Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3506, here are decompositions:

7 + 3499 = 3506
37 + 3469 = 3506
43 + 3463 = 3506
73 + 3433 = 3506
163 + 3343 = 3506
193 + 3313 = 3506
199 + 3307 = 3506
277 + 3229 = 3506

Showing the first eight; more decompositions exist.
