Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140418, here are decompositions:

7 + 140411 = 140418
11 + 140407 = 140418
17 + 140401 = 140418
37 + 140381 = 140418
67 + 140351 = 140418
79 + 140339 = 140418
97 + 140321 = 140418
101 + 140317 = 140418

Showing the first eight; more decompositions exist.
