Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140042, here are decompositions:

43 + 139999 = 140042
61 + 139981 = 140042
73 + 139969 = 140042
103 + 139939 = 140042
151 + 139891 = 140042
181 + 139861 = 140042
211 + 139831 = 140042
229 + 139813 = 140042

Showing the first eight; more decompositions exist.
