Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140380, here are decompositions:

17 + 140363 = 140380
29 + 140351 = 140380
41 + 140339 = 140380
47 + 140333 = 140380
59 + 140321 = 140380
83 + 140297 = 140380
131 + 140249 = 140380
173 + 140207 = 140380

Showing the first eight; more decompositions exist.
