Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140288, here are decompositions:

7 + 140281 = 140288
19 + 140269 = 140288
61 + 140227 = 140288
67 + 140221 = 140288
97 + 140191 = 140288
307 + 139981 = 140288
349 + 139939 = 140288
367 + 139921 = 140288

Showing the first eight; more decompositions exist.
