Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10438, here are decompositions:

5 + 10433 = 10438
11 + 10427 = 10438
47 + 10391 = 10438
101 + 10337 = 10438
107 + 10331 = 10438
137 + 10301 = 10438
149 + 10289 = 10438
167 + 10271 = 10438

Showing the first eight; more decompositions exist.
