Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3524, here are decompositions:

7 + 3517 = 3524
13 + 3511 = 3524
61 + 3463 = 3524
67 + 3457 = 3524
151 + 3373 = 3524
163 + 3361 = 3524
181 + 3343 = 3524
193 + 3331 = 3524

Showing the first eight; more decompositions exist.
