Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3420, here are decompositions:

7 + 3413 = 3420
13 + 3407 = 3420
29 + 3391 = 3420
31 + 3389 = 3420
47 + 3373 = 3420
59 + 3361 = 3420
61 + 3359 = 3420
73 + 3347 = 3420

Showing the first eight; more decompositions exist.
