Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139182, here are decompositions:

5 + 139177 = 139182
13 + 139169 = 139182
59 + 139123 = 139182
61 + 139121 = 139182
73 + 139109 = 139182
103 + 139079 = 139182
149 + 139033 = 139182
223 + 138959 = 139182

Showing the first eight; more decompositions exist.
