Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140928, here are decompositions:

19 + 140909 = 140928
31 + 140897 = 140928
37 + 140891 = 140928
59 + 140869 = 140928
61 + 140867 = 140928
89 + 140839 = 140928
97 + 140831 = 140928
101 + 140827 = 140928

Showing the first eight; more decompositions exist.
