Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625140, here are decompositions:

  • 19 + 8625121 = 8625140
  • 67 + 8625073 = 8625140
  • 127 + 8625013 = 8625140
  • 211 + 8624929 = 8625140
  • 367 + 8624773 = 8625140
  • 463 + 8624677 = 8625140
  • 523 + 8624617 = 8625140
  • 541 + 8624599 = 8625140

Showing the first eight; more decompositions exist.
