Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140730, here are decompositions:

13 + 140717 = 140730
41 + 140689 = 140730
47 + 140683 = 140730
53 + 140677 = 140730
67 + 140663 = 140730
71 + 140659 = 140730
101 + 140629 = 140730
103 + 140627 = 140730

Showing the first eight; more decompositions exist.
