Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140478, here are decompositions:

5 + 140473 = 140478
29 + 140449 = 140478
59 + 140419 = 140478
61 + 140417 = 140478
67 + 140411 = 140478
71 + 140407 = 140478
97 + 140381 = 140478
127 + 140351 = 140478

Showing the first eight; more decompositions exist.
