Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140490, here are decompositions:

13 + 140477 = 140490
17 + 140473 = 140490
37 + 140453 = 140490
41 + 140449 = 140490
47 + 140443 = 140490
67 + 140423 = 140490
71 + 140419 = 140490
73 + 140417 = 140490

Showing the first eight; more decompositions exist.
