Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705120, here are decompositions:

43 + 8705077 = 8705120
79 + 8705041 = 8705120
139 + 8704981 = 8705120
199 + 8704921 = 8705120
211 + 8704909 = 8705120
223 + 8704897 = 8705120
283 + 8704837 = 8705120
337 + 8704783 = 8705120

Showing the first eight; more decompositions exist.
