Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26138, here are decompositions:

19 + 26119 = 26138
31 + 26107 = 26138
97 + 26041 = 26138
109 + 26029 = 26138
139 + 25999 = 26138
157 + 25981 = 26138
199 + 25939 = 26138
271 + 25867 = 26138

Showing the first eight; more decompositions exist.
