Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3438, here are decompositions:

5 + 3433 = 3438
31 + 3407 = 3438
47 + 3391 = 3438
67 + 3371 = 3438
79 + 3359 = 3438
107 + 3331 = 3438
109 + 3329 = 3438
131 + 3307 = 3438

Showing the first eight; more decompositions exist.
