Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615864, here are decompositions:

  • 31 + 8615833 = 8615864
  • 73 + 8615791 = 8615864
  • 97 + 8615767 = 8615864
  • 157 + 8615707 = 8615864
  • 211 + 8615653 = 8615864
  • 241 + 8615623 = 8615864
  • 277 + 8615587 = 8615864
  • 337 + 8615527 = 8615864

Showing the first eight; more decompositions exist.
