Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743120, here are decompositions:

17 + 8743103 = 8743120
41 + 8743079 = 8743120
53 + 8743067 = 8743120
83 + 8743037 = 8743120
101 + 8743019 = 8743120
179 + 8742941 = 8743120
233 + 8742887 = 8743120
263 + 8742857 = 8743120

Showing the first eight; more decompositions exist.
