Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140142, here are decompositions:

19 + 140123 = 140142
31 + 140111 = 140142
71 + 140071 = 140142
73 + 140069 = 140142
89 + 140053 = 140142
151 + 139991 = 140142
173 + 139969 = 140142
199 + 139943 = 140142

Showing the first eight; more decompositions exist.
