Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140724, here are decompositions:

7 + 140717 = 140724
41 + 140683 = 140724
43 + 140681 = 140724
47 + 140677 = 140724
61 + 140663 = 140724
97 + 140627 = 140724
107 + 140617 = 140724
113 + 140611 = 140724

Showing the first eight; more decompositions exist.
