Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140472, here are decompositions:

19 + 140453 = 140472
23 + 140449 = 140472
29 + 140443 = 140472
53 + 140419 = 140472
61 + 140411 = 140472
71 + 140401 = 140472
109 + 140363 = 140472
139 + 140333 = 140472

Showing the first eight; more decompositions exist.
