Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139662, here are decompositions:

43 + 139619 = 139662
53 + 139609 = 139662
71 + 139591 = 139662
73 + 139589 = 139662
151 + 139511 = 139662
179 + 139483 = 139662
223 + 139439 = 139662
233 + 139429 = 139662

Showing the first eight; more decompositions exist.
