Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140808, here are decompositions:

11 + 140797 = 140808
29 + 140779 = 140808
47 + 140761 = 140808
67 + 140741 = 140808
79 + 140729 = 140808
127 + 140681 = 140808
131 + 140677 = 140808
149 + 140659 = 140808

Showing the first eight; more decompositions exist.
