Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139710, here are decompositions:

7 + 139703 = 139710
13 + 139697 = 139710
29 + 139681 = 139710
47 + 139663 = 139710
83 + 139627 = 139710
101 + 139609 = 139710
113 + 139597 = 139710
139 + 139571 = 139710

Showing the first eight; more decompositions exist.
