Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104138, here are decompositions:

19 + 104119 = 104138
31 + 104107 = 104138
79 + 104059 = 104138
157 + 103981 = 104138
271 + 103867 = 104138
337 + 103801 = 104138
439 + 103699 = 104138
457 + 103681 = 104138

Showing the first eight; more decompositions exist.
