Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611100, here are decompositions:

  • 37 + 8611063 = 8611100
  • 67 + 8611033 = 8611100
  • 97 + 8611003 = 8611100
  • 103 + 8610997 = 8611100
  • 139 + 8610961 = 8611100
  • 163 + 8610937 = 8611100
  • 181 + 8610919 = 8611100
  • 229 + 8610871 = 8611100

Showing the first eight; more decompositions exist.
