Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103428, here are decompositions:

5 + 103423 = 103428
7 + 103421 = 103428
19 + 103409 = 103428
29 + 103399 = 103428
37 + 103391 = 103428
41 + 103387 = 103428
71 + 103357 = 103428
79 + 103349 = 103428

Showing the first eight; more decompositions exist.
