Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140660, here are decompositions:

31 + 140629 = 140660
43 + 140617 = 140660
67 + 140593 = 140660
73 + 140587 = 140660
103 + 140557 = 140660
109 + 140551 = 140660
127 + 140533 = 140660
139 + 140521 = 140660

Showing the first eight; more decompositions exist.
