Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139746, here are decompositions:

7 + 139739 = 139746
17 + 139729 = 139746
37 + 139709 = 139746
43 + 139703 = 139746
83 + 139663 = 139746
127 + 139619 = 139746
137 + 139609 = 139746
149 + 139597 = 139746

Showing the first eight; more decompositions exist.
