Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647100, here are decompositions:

  • 37 + 8647063 = 8647100
  • 73 + 8647027 = 8647100
  • 79 + 8647021 = 8647100
  • 139 + 8646961 = 8647100
  • 151 + 8646949 = 8647100
  • 157 + 8646943 = 8647100
  • 211 + 8646889 = 8647100
  • 277 + 8646823 = 8647100

Showing the first eight; more decompositions exist.
