Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611864, here are decompositions:

  • 5 + 8611859 = 8611864
  • 17 + 8611847 = 8611864
  • 71 + 8611793 = 8611864
  • 167 + 8611697 = 8611864
  • 197 + 8611667 = 8611864
  • 251 + 8611613 = 8611864
  • 263 + 8611601 = 8611864
  • 431 + 8611433 = 8611864

Showing the first eight; more decompositions exist.
