Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140840, here are decompositions:

3 + 140837 = 140840
13 + 140827 = 140840
43 + 140797 = 140840
61 + 140779 = 140840
67 + 140773 = 140840
79 + 140761 = 140840
109 + 140731 = 140840
151 + 140689 = 140840

Showing the first eight; more decompositions exist.
