Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740120, here are decompositions:

3 + 8740117 = 8740120
23 + 8740097 = 8740120
83 + 8740037 = 8740120
167 + 8739953 = 8740120
251 + 8739869 = 8740120
269 + 8739851 = 8740120
293 + 8739827 = 8740120
317 + 8739803 = 8740120

Showing the first eight; more decompositions exist.
