Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65138, here are decompositions:

19 + 65119 = 65138
37 + 65101 = 65138
67 + 65071 = 65138
109 + 65029 = 65138
127 + 65011 = 65138
211 + 64927 = 65138
421 + 64717 = 65138
547 + 64591 = 65138

Showing the first eight; more decompositions exist.
