Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139548, here are decompositions:

11 + 139537 = 139548
37 + 139511 = 139548
47 + 139501 = 139548
61 + 139487 = 139548
89 + 139459 = 139548
109 + 139439 = 139548
139 + 139409 = 139548
151 + 139397 = 139548

Showing the first eight; more decompositions exist.
