Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139512, here are decompositions:

11 + 139501 = 139512
19 + 139493 = 139512
29 + 139483 = 139512
53 + 139459 = 139512
73 + 139439 = 139512
83 + 139429 = 139512
89 + 139423 = 139512
103 + 139409 = 139512

Showing the first eight; more decompositions exist.
