Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139032, here are decompositions:

11 + 139021 = 139032
73 + 138959 = 139032
109 + 138923 = 139032
139 + 138893 = 139032
149 + 138883 = 139032
163 + 138869 = 139032
191 + 138841 = 139032
211 + 138821 = 139032

Showing the first eight; more decompositions exist.
