Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139254, here are decompositions:

13 + 139241 = 139254
53 + 139201 = 139254
67 + 139187 = 139254
131 + 139123 = 139254
163 + 139091 = 139254
233 + 139021 = 139254
277 + 138977 = 139254
317 + 138937 = 139254

Showing the first eight; more decompositions exist.
