Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722486, here are decompositions:

  • 263 + 8722223 = 8722486
  • 293 + 8722193 = 8722486
  • 317 + 8722169 = 8722486
  • 389 + 8722097 = 8722486
  • 467 + 8722019 = 8722486
  • 557 + 8721929 = 8722486
  • 569 + 8721917 = 8722486
  • 887 + 8721599 = 8722486

Showing the first eight; more decompositions exist.
