Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3278, here are decompositions:

7 + 3271 = 3278
19 + 3259 = 3278
61 + 3217 = 3278
97 + 3181 = 3278
109 + 3169 = 3278
157 + 3121 = 3278
199 + 3079 = 3278
211 + 3067 = 3278

Showing the first eight; more decompositions exist.
