Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109906, here are decompositions:

3 + 109903 = 109906
23 + 109883 = 109906
47 + 109859 = 109906
59 + 109847 = 109906
113 + 109793 = 109906
233 + 109673 = 109906
317 + 109589 = 109906
359 + 109547 = 109906

Showing the first eight; more decompositions exist.
