Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103912, here are decompositions:

23 + 103889 = 103912
71 + 103841 = 103912
101 + 103811 = 103912
269 + 103643 = 103912
293 + 103619 = 103912
359 + 103553 = 103912
383 + 103529 = 103912
401 + 103511 = 103912

Showing the first eight; more decompositions exist.
