Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67906, here are decompositions:

5 + 67901 = 67906
23 + 67883 = 67906
53 + 67853 = 67906
149 + 67757 = 67906
173 + 67733 = 67906
197 + 67709 = 67906
227 + 67679 = 67906
317 + 67589 = 67906

Showing the first eight; more decompositions exist.
