Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139524, here are decompositions:

13 + 139511 = 139524
23 + 139501 = 139524
31 + 139493 = 139524
37 + 139487 = 139524
41 + 139483 = 139524
67 + 139457 = 139524
101 + 139423 = 139524
127 + 139397 = 139524

Showing the first eight; more decompositions exist.
