Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611090, here are decompositions:

  • 53 + 8611037 = 8611090
  • 197 + 8610893 = 8611090
  • 227 + 8610863 = 8611090
  • 239 + 8610851 = 8611090
  • 263 + 8610827 = 8611090
  • 353 + 8610737 = 8611090
  • 359 + 8610731 = 8611090
  • 431 + 8610659 = 8611090

Showing the first eight; more decompositions exist.
