Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746140, here are decompositions:

23 + 8746117 = 8746140
47 + 8746093 = 8746140
71 + 8746069 = 8746140
103 + 8746037 = 8746140
131 + 8746009 = 8746140
149 + 8745991 = 8746140
211 + 8745929 = 8746140
223 + 8745917 = 8746140

Showing the first eight; more decompositions exist.
