Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3456, here are decompositions:

7 + 3449 = 3456
23 + 3433 = 3456
43 + 3413 = 3456
67 + 3389 = 3456
83 + 3373 = 3456
97 + 3359 = 3456
109 + 3347 = 3456
113 + 3343 = 3456

Showing the first eight; more decompositions exist.
