Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140784, here are decompositions:

5 + 140779 = 140784
11 + 140773 = 140784
23 + 140761 = 140784
43 + 140741 = 140784
53 + 140731 = 140784
67 + 140717 = 140784
101 + 140683 = 140784
103 + 140681 = 140784

Showing the first eight; more decompositions exist.
