Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3440, here are decompositions:

7 + 3433 = 3440
67 + 3373 = 3440
79 + 3361 = 3440
97 + 3343 = 3440
109 + 3331 = 3440
127 + 3313 = 3440
139 + 3301 = 3440
181 + 3259 = 3440

Showing the first eight; more decompositions exist.
