Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140988, here are decompositions:

5 + 140983 = 140988
11 + 140977 = 140988
59 + 140929 = 140988
79 + 140909 = 140988
97 + 140891 = 140988
149 + 140839 = 140988
151 + 140837 = 140988
157 + 140831 = 140988

Showing the first eight; more decompositions exist.
