Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140486, here are decompositions:

13 + 140473 = 140486
37 + 140449 = 140486
43 + 140443 = 140486
67 + 140419 = 140486
79 + 140407 = 140486
223 + 140263 = 140486
433 + 140053 = 140486
487 + 139999 = 140486

Showing the first eight; more decompositions exist.
