Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3428, here are decompositions:

37 + 3391 = 3428
67 + 3361 = 3428
97 + 3331 = 3428
109 + 3319 = 3428
127 + 3301 = 3428
157 + 3271 = 3428
199 + 3229 = 3428
211 + 3217 = 3428

Showing the first eight; more decompositions exist.
