Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139670, here are decompositions:

7 + 139663 = 139670
43 + 139627 = 139670
61 + 139609 = 139670
73 + 139597 = 139670
79 + 139591 = 139670
211 + 139459 = 139670
241 + 139429 = 139670
277 + 139393 = 139670

Showing the first eight; more decompositions exist.
