Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139584, here are decompositions:

13 + 139571 = 139584
37 + 139547 = 139584
47 + 139537 = 139584
73 + 139511 = 139584
83 + 139501 = 139584
97 + 139487 = 139584
101 + 139483 = 139584
127 + 139457 = 139584

Showing the first eight; more decompositions exist.
