Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139770, here are decompositions:

11 + 139759 = 139770
17 + 139753 = 139770
23 + 139747 = 139770
31 + 139739 = 139770
41 + 139729 = 139770
61 + 139709 = 139770
67 + 139703 = 139770
73 + 139697 = 139770

Showing the first eight; more decompositions exist.
