Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8675280, here are decompositions:

  • 59 + 8675221 = 8675280
  • 83 + 8675197 = 8675280
  • 167 + 8675113 = 8675280
  • 181 + 8675099 = 8675280
  • 227 + 8675053 = 8675280
  • 233 + 8675047 = 8675280
  • 269 + 8675011 = 8675280
  • 277 + 8675003 = 8675280

Showing the first eight; more decompositions exist.
