Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3430, here are decompositions:

17 + 3413 = 3430
23 + 3407 = 3430
41 + 3389 = 3430
59 + 3371 = 3430
71 + 3359 = 3430
83 + 3347 = 3430
101 + 3329 = 3430
107 + 3323 = 3430

Showing the first eight; more decompositions exist.
