Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140442, here are decompositions:

19 + 140423 = 140442
23 + 140419 = 140442
31 + 140411 = 140442
41 + 140401 = 140442
61 + 140381 = 140442
79 + 140363 = 140442
103 + 140339 = 140442
109 + 140333 = 140442

Showing the first eight; more decompositions exist.
