Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56906, here are decompositions:

13 + 56893 = 56906
79 + 56827 = 56906
97 + 56809 = 56906
127 + 56779 = 56906
139 + 56767 = 56906
193 + 56713 = 56906
277 + 56629 = 56906
307 + 56599 = 56906

Showing the first eight; more decompositions exist.
