Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3520, here are decompositions:

3 + 3517 = 3520
29 + 3491 = 3520
53 + 3467 = 3520
59 + 3461 = 3520
71 + 3449 = 3520
107 + 3413 = 3520
113 + 3407 = 3520
131 + 3389 = 3520

Showing the first eight; more decompositions exist.
