Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139606, here are decompositions:

17 + 139589 = 139606
59 + 139547 = 139606
113 + 139493 = 139606
149 + 139457 = 139606
167 + 139439 = 139606
197 + 139409 = 139606
239 + 139367 = 139606
263 + 139343 = 139606

Showing the first eight; more decompositions exist.
