Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702644, here are decompositions:

  • 47 + 8702597 = 8702644
  • 53 + 8702591 = 8702644
  • 101 + 8702543 = 8702644
  • 233 + 8702411 = 8702644
  • 257 + 8702387 = 8702644
  • 311 + 8702333 = 8702644
  • 317 + 8702327 = 8702644
  • 593 + 8702051 = 8702644

Showing the first eight; more decompositions exist.
