Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10906, here are decompositions:

3 + 10903 = 10906
17 + 10889 = 10906
23 + 10883 = 10906
47 + 10859 = 10906
53 + 10853 = 10906
59 + 10847 = 10906
107 + 10799 = 10906
167 + 10739 = 10906

Showing the first eight; more decompositions exist.
