Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746120, here are decompositions:

3 + 8746117 = 8746120
83 + 8746037 = 8746120
191 + 8745929 = 8746120
197 + 8745923 = 8746120
239 + 8745881 = 8746120
263 + 8745857 = 8746120
293 + 8745827 = 8746120
353 + 8745767 = 8746120

Showing the first eight; more decompositions exist.
