Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139506, here are decompositions:

5 + 139501 = 139506
13 + 139493 = 139506
19 + 139487 = 139506
23 + 139483 = 139506
47 + 139459 = 139506
67 + 139439 = 139506
83 + 139423 = 139506
97 + 139409 = 139506

Showing the first eight; more decompositions exist.
