Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641164, here are decompositions:

  • 17 + 8641147 = 8641164
  • 31 + 8641133 = 8641164
  • 67 + 8641097 = 8641164
  • 71 + 8641093 = 8641164
  • 101 + 8641063 = 8641164
  • 157 + 8641007 = 8641164
  • 197 + 8640967 = 8641164
  • 277 + 8640887 = 8641164

Showing the first eight; more decompositions exist.
