Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103438, here are decompositions:

17 + 103421 = 103438
29 + 103409 = 103438
47 + 103391 = 103438
89 + 103349 = 103438
131 + 103307 = 103438
149 + 103289 = 103438
347 + 103091 = 103438
359 + 103079 = 103438

Showing the first eight; more decompositions exist.
