Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645122, here are decompositions:

  • 41 + 8645081 = 8645122
  • 113 + 8645009 = 8645122
  • 131 + 8644991 = 8645122
  • 173 + 8644949 = 8645122
  • 419 + 8644703 = 8645122
  • 443 + 8644679 = 8645122
  • 461 + 8644661 = 8645122
  • 569 + 8644553 = 8645122

Showing the first eight; more decompositions exist.
