Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103906, here are decompositions:

3 + 103903 = 103906
17 + 103889 = 103906
137 + 103769 = 103906
263 + 103643 = 103906
293 + 103613 = 103906
353 + 103553 = 103906
449 + 103457 = 103906
557 + 103349 = 103906

Showing the first eight; more decompositions exist.
