Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641492, here are decompositions:

  • 23 + 8641469 = 8641492
  • 59 + 8641433 = 8641492
  • 71 + 8641421 = 8641492
  • 131 + 8641361 = 8641492
  • 173 + 8641319 = 8641492
  • 191 + 8641301 = 8641492
  • 281 + 8641211 = 8641492
  • 359 + 8641133 = 8641492

Showing the first eight; more decompositions exist.
