Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140642, here are decompositions:

3 + 140639 = 140642
13 + 140629 = 140642
31 + 140611 = 140642
109 + 140533 = 140642
193 + 140449 = 140642
199 + 140443 = 140642
223 + 140419 = 140642
241 + 140401 = 140642

Showing the first eight; more decompositions exist.
