Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140904, here are decompositions:

7 + 140897 = 140904
11 + 140893 = 140904
13 + 140891 = 140904
37 + 140867 = 140904
41 + 140863 = 140904
67 + 140837 = 140904
73 + 140831 = 140904
107 + 140797 = 140904

Showing the first eight; more decompositions exist.
