Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47906, here are decompositions:

3 + 47903 = 47906
37 + 47869 = 47906
97 + 47809 = 47906
109 + 47797 = 47906
127 + 47779 = 47906
163 + 47743 = 47906
193 + 47713 = 47906
277 + 47629 = 47906

Showing the first eight; more decompositions exist.
