Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140670, here are decompositions:

7 + 140663 = 140670
11 + 140659 = 140670
31 + 140639 = 140670
41 + 140629 = 140670
43 + 140627 = 140670
53 + 140617 = 140670
59 + 140611 = 140670
67 + 140603 = 140670

Showing the first eight; more decompositions exist.
