Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140788, here are decompositions:

29 + 140759 = 140788
47 + 140741 = 140788
59 + 140729 = 140788
71 + 140717 = 140788
107 + 140681 = 140788
149 + 140639 = 140788
239 + 140549 = 140788
311 + 140477 = 140788

Showing the first eight; more decompositions exist.
