Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140180, here are decompositions:

3 + 140177 = 140180
13 + 140167 = 140180
37 + 140143 = 140180
109 + 140071 = 140180
127 + 140053 = 140180
181 + 139999 = 140180
193 + 139987 = 140180
199 + 139981 = 140180

Showing the first eight; more decompositions exist.
