Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3512, here are decompositions:

13 + 3499 = 3512
43 + 3469 = 3512
79 + 3433 = 3512
139 + 3373 = 3512
151 + 3361 = 3512
181 + 3331 = 3512
193 + 3319 = 3512
199 + 3313 = 3512

Showing the first eight; more decompositions exist.
