Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111906, here are decompositions:

13 + 111893 = 111906
37 + 111869 = 111906
43 + 111863 = 111906
59 + 111847 = 111906
73 + 111833 = 111906
79 + 111827 = 111906
107 + 111799 = 111906
127 + 111779 = 111906

Showing the first eight; more decompositions exist.
