Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615828, here are decompositions:

  • 19 + 8615809 = 8615828
  • 37 + 8615791 = 8615828
  • 61 + 8615767 = 8615828
  • 79 + 8615749 = 8615828
  • 241 + 8615587 = 8615828
  • 337 + 8615491 = 8615828
  • 349 + 8615479 = 8615828
  • 367 + 8615461 = 8615828

Showing the first eight; more decompositions exist.
