Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641146, here are decompositions:

  • 13 + 8641133 = 8641146
  • 53 + 8641093 = 8641146
  • 67 + 8641079 = 8641146
  • 83 + 8641063 = 8641146
  • 139 + 8641007 = 8641146
  • 179 + 8640967 = 8641146
  • 197 + 8640949 = 8641146
  • 257 + 8640889 = 8641146

Showing the first eight; more decompositions exist.
