Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140838, here are decompositions:

7 + 140831 = 140838
11 + 140827 = 140838
41 + 140797 = 140838
59 + 140779 = 140838
79 + 140759 = 140838
97 + 140741 = 140838
107 + 140731 = 140838
109 + 140729 = 140838

Showing the first eight; more decompositions exist.
